Expand description

RSA PKCS1 V1.5 SHA-256 signature verify.

The signature * s - of the input message * m - is verified.

s - The signature.
s_len - Length of * s - .
m - The signed message.
m_len - Length of * m - .
pk - A valid RSA public key.
mem - The working memory. Length OCRYPTO_RSA_PUB_MEM_SIZE(bits).

Returns 0 If the signature is valid. Returns -1 If verification failed.

@remark The key * pk - should be initialized with * ocrypto_rsa_init_pub_key - . @remark * mem - may be same as * s - or * m - .
