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

RSA PSS SHA-256 sign with CRT acceleration.

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

Parameters

[out]	s	The generated signature.
	s_len	Length of m.
	m	The message to be signed.
	m_len	Length of m.
	salt	The salt to be used.
	salt_len	Length of salt.
	key	A valid RSA secret key with CRT coefficients.
	mem	The working memory. Length OCRYPTO_RSA_CRT_MEM_SIZE(bits).

Return values

-2	If the salt is too long.
0	On success.

Remarks

The key key should be initialized with ocrypto_rsa_init_crt_key.

s, m, and mem may be same.
