@brief AWS SigV4 Library
|
||||
|
||||
The AWS SigV4 Library is a standalone library for generating signatures
|
||||
and authorization headers according to the specifications of the AWS Signature
|
||||
Version 4 signing process. This library aids applications in sending direct
|
||||
HTTP requests to AWS services requiring SigV4 authentication. The library is
|
||||
written in C and designed to be compliant with ISO C90 and MISRA C and has no
|
||||
dependencies on any additional libraries other than the standard C library.

||||

||||

||||
@brief SigV4 Library Design
|
||||
|
||||
<h3>Memory Usage</h3>
|
||||
<p>
|
||||
All functions in the SigV4 library operate only on the buffers provided and use only
|
||||
local variables on the stack.
|
||||
</p>
|
||||
|
||||
<h3>Compliance & Coverage</h3>
|
||||
|
||||
<p>
|
||||
The SIGV4 library is designed to be compliant with ISO C90 and MISRA C:2012.
|
||||
All functions are written to have low complexity scores. Unit tests and CBMC
|
||||
proofs are written to cover every path of execution and achieve 100% branch
|
||||
coverage.
|
||||
</p>
|
||||
|
||||
The diagram below demonstrates the happy path an application can take to use
|
||||
the SigV4 library to interact with AWS Services that support SigV4 authentication via HTTP requests.

* @page sigv4_porting Porting Guide
|
||||
* @brief Guide for porting the AWS SigV4 Library to a new
|
||||
* platform.
|
||||
*
|
||||
* To use the AWS SigV4 library, a platform must implement the following
|
||||
* components:
|
||||
* 1. [Configuration Macros](@ref sigv4_config_macros)
|
||||
* 2. [Crypto Interface](@ref sigv4_porting_cryptointerface)
|
||||
*
|
||||
* @section sigv4_config_macros Configuration Macros
|
||||
* @brief Configuration macros that can be set in the config header
|
||||
* `sigv4_config.h`, or passed in as compiler options.
|
||||
*
|
||||
* The following optional logging macros are used throughout the library:
|
||||
* - @ref LogError
|
||||
* - @ref LogWarn
|
||||
* - @ref LogInfo
|
||||
* - @ref LogDebug
|
||||
*
|
||||
* @see [Configurations](@ref sigv4_config) for more information.
|
||||
*
|
||||
* @note Regardless of whether the above macros are defined in
|
||||
* `sigv4_config.h` or passed as compiler options, by default the
|
||||
* `sigv4_config.h` file is needed to build the AWS SigV4 Library. To disable this requirement and build the library with
|
||||
* default configuration values, provide
|
||||
* `SIGV4_DO_NOT_USE_CUSTOM_CONFIG` as a compile time preprocessor
|
||||
* macro.
|
||||
*
|
||||
* @section sigv4_porting_cryptointerface Crypto Interface
|
||||
* @brief The AWS SigV4 library relies on the implementation of crypto interface
|
||||
* to provide hash functions used in generating the Authorization header by the library.
|
||||
*
|
||||
* A port must implement functions corresponding to the
|
||||
* following functions pointers:
|
||||
* - [Hash Initialize]: A function to initialize the Hash Context.
|
||||
* @code
|
||||
* int32_t ( * hashInit )( void * pHashContext );
|
||||
* @endcode
|
||||
* - [Hash Update]: A function to update the hash to be calculated with more input data.
|
||||
* @code
|
||||
* int32_t ( * hashUpdate )( void * pHashContext,
|
||||
* const uint8_t * pInput,
|
||||
* size_t inputLen );
|
||||
* @endcode
|
||||
* - [Hash Final]: A function to calculate the final binary digest of the hash from the context.
|
||||
* @code
|
||||
* int32_t ( * hashFinal )( void * pHashContext,
|
||||
* uint8_t * pOutput,
|
||||
* size_t outputLen );
|
||||
* @endcode
|
||||
*
|
||||
* The above three functions take in a pointer to pHashContext which defines the context used
|
||||
* by the above function in calculating the hash. The HashContext must also be
|
||||
* defined by the user's implementation and ought to contain any information
|
||||
* necessary to calculate the hash.
|
||||
* @code
|
||||
* void * pHashContext;
|
||||
* @endcode
|
||||
*
|
||||
* A port must also define the following:
|
||||
* - [Hash Block Length]: The block length of the hash function implemented by the user.
|
||||
* @code
|
||||
* size_t hashBlockLen;
|
||||
* @endcode
|
||||
*
|
||||
* - [Hash Digest Length]: The digest length of the hash function implemented by the user.
|
||||
* @code
|
||||
* size_t hashDigestLen;
|
||||
* @endcode
