ocrypto_rsa2048_pkcs1_v15_sha256_crt_sign()

int ocrypto_rsa2048_pkcs1_v15_sha256_crt_sign	(	uint8_t	s[256],
		const uint8_t *	m,
		size_t	mlen,
		const ocrypto_rsa2048_crt_key *	sk )

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

2048-bit RSA PKCS1 V1.5 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.
	sk	A valid 2048-bit RSA secret key with CRT coefficients.

Return values

0

Remarks

The key sk should be initialized with ocrypto_rsa2048_init_crt_key.

s may be same as m.
