Detailed Description

RSA.

Function Documentation

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

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

struct crypto_rsa_key* crypto_rsa_import_private_key	(	const u8 *	buf,
		size_t	len
	)

Import an RSA private key.

Parameters

buf	Key buffer (DER encoded RSA private key)
len	Key buffer length in bytes

struct crypto_rsa_key* crypto_rsa_import_public_key	(	const u8 *	buf,
		size_t	len
	)

Import an RSA public key.

Parameters

buf	Key buffer (DER encoded RSA public key)
len	Key buffer length in bytes
