RSA PKCS1 V1.5 SHA-256 sign.

The message m is signed and the signature returned in s.

Parameters

[out]	s	The generated signature.
	s_len	Length of s.
	m	The message to be signed.
	m_len	Length of m.
	key	A valid RSA secret key.
	mem	The working memory. Length OCRYPTO_RSA_MEM_SIZE(bits).

Return values

0

Remarks

The key key should be initialized with ocrypto_rsa_init_key.

s, m, and mem may be same.
