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

2048-bit RSA PSS SHA-256 sign with CRT acceleration.

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

Parameters

[out]	s	The generated 256-byte signature.
	m	The message to be signed.
	mlen	Length of m.
	salt	The salt to be used.
	slen	Length of salt.
	sk	A valid 2048-bit RSA secret key with CRT coefficients.

Return values

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

Remarks

The key sk should be initialized with ocrypto_rsa2048_init_crt_key.

s may be same as m.
