mbedtls_pk_verify_ext() function
Verify signature, with options. (Includes verification of the padding depending on type.)
Syntax
int mbedtls_pk_verify_ext( mbedtls_pk_type_t type,
const void *options,
mbedtls_pk_context *ctx,
mbedtls_md_type_t md_alg,
const unsigned char *hash,
size_t hash_len,
const unsigned char *sig,
size_t sig_len );
Implemented in ![]()
pk.c:299
Return value
0 on success (signature is valid), #MBEDTLS_ERR_PK_TYPE_MISMATCH if the PK context can't be used for this type of signatures, #MBEDTLS_ERR_PK_SIG_LEN_MISMATCH if there is a valid signature in sig but its length is less than \p siglen, or a specific error code.
Notes
If hash_len is 0, then the length associated with md_alg is used instead, or an error returned if it is invalid. md_alg may be MBEDTLS_MD_NONE, only if hash_len != 0 If type is MBEDTLS_PK_RSASSA_PSS, then options must point to a mbedtls_pk_rsassa_pss_options structure, otherwise it must be NULL.
