NAME

shishi_aes_cts - API function

SYNOPSIS

#include <shishi.h>

int shishi_aes_cts(Shishi * handle, int decryptp, const char * key, size_t keylen, const char iv[16], char * ivout[16], const char * in, size_t inlen, char ** out);

ARGUMENTS

Shishi * handle: shishi handle as allocated by shishi_init().
int decryptp: 0 to indicate encryption, non-0 to indicate decryption.
const char * key: input character array with key to use.
size_t keylen: length of input character array with key to use.
const char iv[16]: input character array with initialization vector to use, or NULL.
char * ivout[16]: output character array with updated initialization vector, or NULL.
const char * in: input character array of data to encrypt/decrypt.
size_t inlen: length of input character array of data to encrypt/decrypt.
char ** out: newly allocated character array with encrypted/decrypted data.

DESCRIPTION

Encrypt or decrypt data (depending on decryptp) using AES in CBC-CTS mode. The length of the key, keylen, decide if AES 128 or AES 256 should be used. The out buffer must be deallocated by the caller.

RETURN VALUE

Returns SHISHI_OK iff successful.
