Function Documentation

int crypto_rsa_exptmod	(	const u8 *	in,
		size_t	inlen,
		u8 *	out,
		size_t *	outlen,
		struct crypto_rsa_key *	key,
		int	use_private
	)

RSA modular exponentiation.

Parameters:

	in	Input data
	inlen	Input data length
	out	Buffer for output data
	outlen	Maximum size of the output buffer and used size on success
	key	RSA key
	use_private	1 = Use RSA private key, 0 = Use RSA public key

Returns:

0 on success, -1 on failure

void crypto_rsa_free

(

struct crypto_rsa_key *

key

)

Free RSA key.

Parameters:

key

RSA key to be freed

This function frees an RSA key imported with either crypto_rsa_import_public_key() or crypto_rsa_import_private_key().

size_t crypto_rsa_get_modulus_len

(

struct crypto_rsa_key *

key

)

Get the modulus length of the RSA key.

Parameters:

key

RSA key

Returns:

Modulus length of the key
