int ocrypto_rsa1024_pkcs1_v15_sha256_sign	(	uint8_t	s[128],
		const uint8_t *	m,
		size_t	m_len,
		const ocrypto_rsa1024_key *	sk
	)

#include <crypto/nrf_oberon/include/ocrypto_rsa.h>

1024-bit RSA PKCS1 V1.5 SHA-256 sign.

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

Parameters

[out]	s	The generated 128-byte signature.
	m	The message to be signed.
	m_len	Length of m.
	sk	A valid 1024-bit RSA secret key.

Return values

0

Remarks

The key sk should be initialized with ocrypto_rsa1024_init_key.

s may be same as m.
