Carries out the RSA-SSA signature generation with EMSA-PSS encoding scheme. | |
This function carries out the RSA-SSA signature generation with EMSA-PSS encoding scheme defined in | |
RFC 8017. | |
Mask generation function is the same as the message digest algorithm. | |
If the Signature buffer is too small to hold the contents of signature, FALSE | |
is returned and SigSize is set to the required buffer size to obtain the signature. | |
If RsaContext is NULL, then return FALSE. | |
If Message is NULL, then return FALSE. | |
If MsgSize is zero or > INT_MAX, then return FALSE. | |
If DigestLen is NOT 32, 48 or 64, return FALSE. | |
If SaltLen is not equal to DigestLen, then return FALSE. | |
If SigSize is large enough but Signature is NULL, then return FALSE. | |
If this interface is not supported, then return FALSE. | |
@param[in] RsaContext Pointer to RSA context for signature generation. | |
@param[in] Message Pointer to octet message to be signed. | |
@param[in] MsgSize Size of the message in bytes. | |
@param[in] DigestLen Length of the digest in bytes to be used for RSA signature operation. | |
@param[in] SaltLen Length of the salt in bytes to be used for PSS encoding. | |
@param[out] Signature Pointer to buffer to receive RSA PSS signature. | |
@param[in, out] SigSize On input, the size of Signature buffer in bytes. | |
On output, the size of data returned in Signature buffer in bytes. | |
@retval TRUE Signature successfully generated in RSASSA-PSS. | |
@retval FALSE Signature generation failed. | |
@retval FALSE SigSize is too small. | |
@retval FALSE This interface is not supported. | |
