mbedtls_pk_verify() function
Verify signature (including padding if relevant).
Syntax
int mbedtls_pk_verify( 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:288
Return value
0 on success (signature is valid), #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
For RSA keys, the default padding type is PKCS#1 v1.5. Use \c mbedtls_pk_verify_ext( MBEDTLS_PK_RSASSA_PSS, ... ) to verify RSASSA_PSS signatures. 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
