MBEDTLS_RSA_ALT_HELPERS_H macro

\file rsa_alt_helpers.h 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.
