/**
* \file aes.h
*
* \brief This file contains AES definitions and functions.
*
* The Advanced Encryption Standard (AES) specifies a FIPS-approved
* cryptographic algorithm that can be used to protect electronic
* data.
*
* The AES algorithm is a symmetric block cipher that can
* encrypt and decrypt information. For more information, see
* <em>FIPS Publication 197: Advanced Encryption Standard</em> and
* <em>ISO/IEC 18033-2:2006: Information technology -- Security
* techniques -- Encryption algorithms -- Part 2: Asymmetric
* ciphers</em>.
*
* The AES-XTS block mode is standardized by NIST SP 800-38E
* <https://nvlpubs.nist.gov/nistpubs/legacy/sp/nistspecialpublication800-38e.pdf>
* and described in detail by IEEE P1619
* <https://ieeexplore.ieee.org/servlet/opac?punumber=4375278>.

* \brief This function performs an AES-CTR encryption or decryption
* operation.
*
* This function performs the operation defined in the \p mode
* parameter (encrypt/decrypt), on the input data buffer
* defined in the \p input parameter.
*
* Due to the nature of CTR, you must use the same key schedule
* for both encryption and decryption operations. Therefore, you
* must use the context initialized with mbedtls_aes_setkey_enc()
* for both #MBEDTLS_AES_ENCRYPT and #MBEDTLS_AES_DECRYPT.
*
* \warning You must never reuse a nonce value with the same key. Doing so
* would void the encryption for the two messages encrypted with
* the same nonce and key.
*
* There are two common strategies for managing nonces with CTR:
*
* 1. You can handle everything as a single message processed over
* successive calls to this function. In that case, you want to
* set \p nonce_counter and \p nc_off to 0 for the first call, and
* then preserve the values of \p nonce_counter, \p nc_off and \p
* stream_block across calls to this function as they will be
* updated by this function.
*
* With this strategy, you must not encrypt more than 2**128
* blocks of data with the same key.
*
* 2. You can encrypt separate messages by dividing the \p
* nonce_counter buffer in two areas: the first one used for a
* per-message nonce, handled by yourself, and the second one
* updated by this function internally.
*
* For example, you might reserve the first 12 bytes for the
* per-message nonce, and the last 4 bytes for internal use. In that
* case, before calling this function on a new message you need to
* set the first 12 bytes of \p nonce_counter to your chosen nonce
* value, the last 4 to 0, and \p nc_off to 0 (which will cause \p
* stream_block to be ignored). That way, you can encrypt at most
* 2**96 messages of up to 2**32 blocks each with the same key.
*
* The per-message nonce (or information sufficient to reconstruct
* it) needs to be communicated with the ciphertext and must be unique.
* The recommended way to ensure uniqueness is to use a message
* counter. An alternative is to generate random nonces, but this
* limits the number of messages that can be securely encrypted:
* for example, with 96-bit random nonces, you should not encrypt
* more than 2**32 messages with the same key.
*
* Note that for both stategies, sizes are measured in blocks and
* that an AES block is 16 bytes.
*
* \warning Upon return, \p stream_block contains sensitive data. Its
* content must not be written to insecure storage and should be
* securely discarded as soon as it's no longer needed.
*
* \param ctx The AES context to use for encryption or decryption.
* It must be initialized and bound to a key.
* \param length The length of the input data.
* \param nc_off The offset in the current \p stream_block, for
* resuming within the current cipher stream. The
* offset pointer should be 0 at the start of a stream.
* It must point to a valid \c size_t.
* \param nonce_counter The 128-bit nonce and counter.
* It must be a readable-writeable buffer of \c 16 Bytes.
* \param stream_block The saved stream block for resuming. This is
* overwritten by the function.
* It must be a readable-writeable buffer of \c 16 Bytes.
* \param input The buffer holding the input data.
* It must be readable and of size \p length Bytes.

* \brief This function performs an ARIA-CTR encryption or decryption
* operation.
*
* This function performs the operation defined in the \p mode
* parameter (encrypt/decrypt), on the input data buffer
* defined in the \p input parameter.
*
* Due to the nature of CTR, you must use the same key schedule
* for both encryption and decryption operations. Therefore, you
* must use the context initialized with mbedtls_aria_setkey_enc()
* for both #MBEDTLS_ARIA_ENCRYPT and #MBEDTLS_ARIA_DECRYPT.
*
* \warning You must never reuse a nonce value with the same key. Doing so
* would void the encryption for the two messages encrypted with
* the same nonce and key.
*
* There are two common strategies for managing nonces with CTR:
*
* 1. You can handle everything as a single message processed over
* successive calls to this function. In that case, you want to
* set \p nonce_counter and \p nc_off to 0 for the first call, and
* then preserve the values of \p nonce_counter, \p nc_off and \p
* stream_block across calls to this function as they will be
* updated by this function.
*
* With this strategy, you must not encrypt more than 2**128
* blocks of data with the same key.
*
* 2. You can encrypt separate messages by dividing the \p
* nonce_counter buffer in two areas: the first one used for a
* per-message nonce, handled by yourself, and the second one
* updated by this function internally.
*
* For example, you might reserve the first 12 bytes for the
* per-message nonce, and the last 4 bytes for internal use. In that
* case, before calling this function on a new message you need to
* set the first 12 bytes of \p nonce_counter to your chosen nonce
* value, the last 4 to 0, and \p nc_off to 0 (which will cause \p
* stream_block to be ignored). That way, you can encrypt at most
* 2**96 messages of up to 2**32 blocks each with the same key.
*
* The per-message nonce (or information sufficient to reconstruct
* it) needs to be communicated with the ciphertext and must be unique.
* The recommended way to ensure uniqueness is to use a message
* counter. An alternative is to generate random nonces, but this
* limits the number of messages that can be securely encrypted:
* for example, with 96-bit random nonces, you should not encrypt
* more than 2**32 messages with the same key.
*
* Note that for both stategies, sizes are measured in blocks and
* that an ARIA block is 16 bytes.
*
* \warning Upon return, \p stream_block contains sensitive data. Its
* content must not be written to insecure storage and should be
* securely discarded as soon as it's no longer needed.
*
* \param ctx The ARIA context to use for encryption or decryption.
* This must be initialized and bound to a key.
* \param length The length of the input data \p input in Bytes.
* \param nc_off The offset in Bytes in the current \p stream_block,
* for resuming within the current cipher stream. The
* offset pointer should be \c 0 at the start of a
* stream. This must not be larger than \c 15 Bytes.
* \param nonce_counter The 128-bit nonce and counter. This must point to
* a read/write buffer of length \c 16 bytes.
* \param stream_block The saved stream block for resuming. This must
* point to a read/write buffer of length \c 16 bytes.
* This is overwritten by the function.
* \param input The buffer holding the input data. This must
* be a readable buffer of length \p length Bytes.
* \param output The buffer holding the output data. This must
* be a writable buffer of length \p length Bytes.

* \brief Perform a Blowfish-CTR buffer encryption/decryption operation.
*
* \warning You must never reuse a nonce value with the same key. Doing so
* would void the encryption for the two messages encrypted with
* the same nonce and key.
*
* There are two common strategies for managing nonces with CTR:
*
* 1. You can handle everything as a single message processed over
* successive calls to this function. In that case, you want to
* set \p nonce_counter and \p nc_off to 0 for the first call, and
* then preserve the values of \p nonce_counter, \p nc_off and \p
* stream_block across calls to this function as they will be
* updated by this function.
*
* With this strategy, you must not encrypt more than 2**64
* blocks of data with the same key.
*
* 2. You can encrypt separate messages by dividing the \p
* nonce_counter buffer in two areas: the first one used for a
* per-message nonce, handled by yourself, and the second one
* updated by this function internally.
*
* For example, you might reserve the first 4 bytes for the
* per-message nonce, and the last 4 bytes for internal use. In that
* case, before calling this function on a new message you need to
* set the first 4 bytes of \p nonce_counter to your chosen nonce
* value, the last 4 to 0, and \p nc_off to 0 (which will cause \p
* stream_block to be ignored). That way, you can encrypt at most
* 2**32 messages of up to 2**32 blocks each with the same key.
*
* The per-message nonce (or information sufficient to reconstruct
* it) needs to be communicated with the ciphertext and must be unique.
* The recommended way to ensure uniqueness is to use a message
* counter.
*
* Note that for both stategies, sizes are measured in blocks and
* that a Blowfish block is 8 bytes.
*
* \warning Upon return, \p stream_block contains sensitive data. Its
* content must not be written to insecure storage and should be
* securely discarded as soon as it's no longer needed.
*
* \param ctx The Blowfish context to use. This must be initialized
* and bound to a key.
* \param length The length of the input data in Bytes.
* \param nc_off The offset in the current stream_block (for resuming
* within current cipher stream). The offset pointer
* should be \c 0 at the start of a stream and must be
* smaller than \c 8. It is updated by this function.
* \param nonce_counter The 64-bit nonce and counter. This must point to a
* read/write buffer of length \c 8 Bytes.
* \param stream_block The saved stream-block for resuming. This must point to
* a read/write buffer of length \c 8 Bytes.
* \param input The input data. This must be a readable buffer of
* length \p length Bytes.
* \param output The output data. This must be a writable buffer of
* length \p length Bytes.

*
* \warning You must never reuse a nonce value with the same key. Doing so
* would void the encryption for the two messages encrypted with
* the same nonce and key.
*
* There are two common strategies for managing nonces with CTR:
*
* 1. You can handle everything as a single message processed over
* successive calls to this function. In that case, you want to
* set \p nonce_counter and \p nc_off to 0 for the first call, and
* then preserve the values of \p nonce_counter, \p nc_off and \p
* stream_block across calls to this function as they will be
* updated by this function.
*
* With this strategy, you must not encrypt more than 2**128
* blocks of data with the same key.
*
* 2. You can encrypt separate messages by dividing the \p
* nonce_counter buffer in two areas: the first one used for a
* per-message nonce, handled by yourself, and the second one
* updated by this function internally.
*
* For example, you might reserve the first \c 12 Bytes for the
* per-message nonce, and the last \c 4 Bytes for internal use.
* In that case, before calling this function on a new message you
* need to set the first \c 12 Bytes of \p nonce_counter to your
* chosen nonce value, the last four to \c 0, and \p nc_off to \c 0
* (which will cause \p stream_block to be ignored). That way, you
* can encrypt at most \c 2**96 messages of up to \c 2**32 blocks
* each with the same key.
*
* The per-message nonce (or information sufficient to reconstruct
* it) needs to be communicated with the ciphertext and must be
* unique. The recommended way to ensure uniqueness is to use a
* message counter. An alternative is to generate random nonces,
* but this limits the number of messages that can be securely
* encrypted: for example, with 96-bit random nonces, you should
* not encrypt more than 2**32 messages with the same key.
*
* Note that for both stategies, sizes are measured in blocks and
* that a CAMELLIA block is \c 16 Bytes.
*
* \warning Upon return, \p stream_block contains sensitive data. Its
* content must not be written to insecure storage and should be
* securely discarded as soon as it's no longer needed.

/**
* \file ccm.h
*
* \brief This file provides an API for the CCM authenticated encryption
* mode for block ciphers.
*
* CCM combines Counter mode encryption with CBC-MAC authentication
* for 128-bit block ciphers.
*
* Input to CCM includes the following elements:
* <ul><li>Payload - data that is both authenticated and encrypted.</li>
* <li>Associated data (Adata) - data that is authenticated but not
* encrypted, For example, a header.</li>
* <li>Nonce - A unique value that is assigned to the payload and the
* associated data.</li></ul>
*
* Definition of CCM:
* http://csrc.nist.gov/publications/nistpubs/800-38C/SP800-38C_updated-July20_2007.pdf
* RFC 3610 "Counter with CBC-MAC (CCM)"
*
* Related:
* RFC 5116 "An Interface and Algorithms for Authenticated Encryption"
*
* Definition of CCM*:
* IEEE 802.15.4 - IEEE Standard for Local and metropolitan area networks
* Integer representation is fixed most-significant-octet-first order and
* the representation of octets is most-significant-bit-first order. This is
* consistent with RFC 3610.

/**
* \file ctr_drbg.h
*
* \brief This file contains CTR_DRBG definitions and functions.
*
* CTR_DRBG is a standardized way of building a PRNG from a block-cipher
* in counter mode operation, as defined in <em>NIST SP 800-90A:
* Recommendation for Random Number Generation Using Deterministic Random
* Bit Generators</em>.
*
* The Mbed TLS implementation of CTR_DRBG uses AES-256 (default) or AES-128
* as the underlying block cipher.
*
* \warning Using 128-bit keys for CTR_DRBG limits the security of generated
* keys and operations that use random values generated to 128-bit security.

* Error code layout.
*
* Currently we try to keep all error codes within the negative space of 16
* bits signed integers to support all platforms (-0x0001 - -0x7FFF). In
* addition we'd like to give two layers of information on the error if
* possible.
*
* For that purpose the error codes are segmented in the following manner:
*
* 16 bit error code bit-segmentation
*
* 1 bit - Unused (sign bit)
* 3 bits - High level module ID
* 5 bits - Module-dependent error code
* 7 bits - Low level module errors
*
* For historical reasons, low-level error codes are divided in even and odd,
* even codes were assigned first, and -1 is reserved for other errors.

* \brief This file contains the definitions and functions of the
* Mbed TLS platform abstraction layer.
*
* The platform abstraction layer removes the need for the library
* to directly link to standard C library functions or operating
* system services, making the library easier to port and embed.
* Application developers and users of the library can provide their own
* implementations of these functions, or implementations specific to
* their platform, which can be statically linked to the library or
* dynamically configured at runtime.

*
* \brief This file contains Poly1305 definitions and functions.
*
* Poly1305 is a one-time message authenticator that can be used to
* authenticate messages. Poly1305-AES was created by Daniel
* Bernstein https://cr.yp.to/mac/poly1305-20050329.pdf The generic
* Poly1305 algorithm (not tied to AES) was also standardized in RFC
* 7539.

/**
* \file rsa_internal.h
*
* \brief Context-independent RSA helper functions
*
* This module declares some RSA-related helper functions useful when
* implementing the RSA interface. These functions are provided in a separate
* compilation unit in order to make it easy for designers of alternative RSA
* implementations to use them in their own code, as it is conceived that the
* functionality they provide will be necessary for most complete
* implementations.
*
* End-users of Mbed TLS who are not providing their own alternative RSA
* implementations should not use these functions directly, and should instead
* use only the functions declared in rsa.h.
*
* The interface provided by this module will be maintained through LTS (Long
* Term Support) branches of Mbed TLS, but may otherwise be subject to change,
* and must be considered an internal interface of the library.
*
* There are two classes of helper functions:
*
* (1) Parameter-generating helpers. These are:
* - mbedtls_rsa_deduce_primes
* - mbedtls_rsa_deduce_private_exponent
* - mbedtls_rsa_deduce_crt
* Each of these functions takes a set of core RSA parameters and
* generates some other, or CRT related parameters.
*
* (2) Parameter-checking helpers. These are:
* - mbedtls_rsa_validate_params
* - mbedtls_rsa_validate_crt
* They take a set of core or CRT related RSA parameters and check their
* validity.
*

* can be problemmatic to manage on embedded platforms, the inputs are passed
* to the driver via a function, `psa_drv_se_key_derivation_collateral`, that
* is called multiple times with different `collateral_id`s. Thus, for a key
* derivation algorithm that required 3 paramter inputs, the flow would look
* something like:
* ~~~~~~~~~~~~~{.c}
* psa_drv_se_key_derivation_setup(kdf_algorithm, source_key, dest_key_size_bytes);
* psa_drv_se_key_derivation_collateral(kdf_algorithm_collateral_id_0,
* p_collateral_0,
* collateral_0_size);
* psa_drv_se_key_derivation_collateral(kdf_algorithm_collateral_id_1,
* p_collateral_1,
* collateral_1_size);
* psa_drv_se_key_derivation_collateral(kdf_algorithm_collateral_id_2,
* p_collateral_2,
* collateral_2_size);
* psa_drv_se_key_derivation_derive();
* ~~~~~~~~~~~~~
*
* key agreement example:
* ~~~~~~~~~~~~~{.c}
* psa_drv_se_key_derivation_setup(alg, source_key. dest_key_size_bytes);
* psa_drv_se_key_derivation_collateral(DHE_PUBKEY, p_pubkey, pubkey_size);
* psa_drv_se_key_derivation_export(p_session_key,
* session_key_size,
* &session_key_length);

* \brief PSA cryptography module: Mbed TLS buffer size macros
*
* \note This file may not be included directly. Applications must
* include psa/crypto.h.
*
* This file contains the definitions of macros that are useful to
* compute buffer sizes. The signatures and semantics of these macros
* are standardized, but the definitions are not, because they depend on
* the available algorithms and, in some cases, on permitted tolerances
* on buffer sizes.
*
* In implementations with isolation between the application and the
* cryptography module, implementers should take care to ensure that
* the definitions that are exposed to applications match what the
* module implements.
*
* Macros that compute sizes whose values do not depend on the
* implementation are in crypto.h.
