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 Definition at line 254 of file rsa.c. Here is the call graph for this function:

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(). Definition at line 352 of file rsa.c. Here is the call graph for this function:

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 Definition at line 237 of file rsa.c. Here is the call graph for this function:

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 Returns: Pointer to the private key or NULL on failure Definition at line 136 of file rsa.c. Here is the call graph for this function:

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 Returns: Pointer to the public key or NULL on failure Definition at line 71 of file rsa.c. Here is the call graph for this function:
