* Parameters:
* - md_alg: Identifies the hash algorithm used to generate the given hash;
* MBEDTLS_MD_NONE if raw data are signed.
* MBEDTLS_MD_NONE if raw data is signed.
* - hashlen: Length of hash in case hashlen is MBEDTLS_MD_NONE.
* - hash: Buffer containing the hashed message.
* - sig_len: Length of the encoded message.
* - hash: Buffer containing the hashed message or the raw data.
* - dst_len: Length of the encoded message.
* - dst: Buffer to hold the encoded message.
*
* Assumptions:
* - hash has size hashlen if md_alg == MBEDTLS_MD_NONE.
* - hash has size corresponding to md_alg if md_alg != MBEDTLS_MD_NONE.
* - dst points to a buffer of size at least sig_len.
* - dst points to a buffer of size at least dst_len.
