NAME

shishi_arcfour - API function

SYNOPSIS

#include <shishi.h>

int shishi_arcfour(Shishi * handle, int decryptp, const char * key, size_t keylen, const char iv[258], char * ivout[258], 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 key array.
const char iv[258]: input character array with initialization vector to use, or NULL.
char * ivout[258]: 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 ARCFOUR. The out buffer must be deallocated by the caller.

The "initialization vector" used here is the concatenation of the sbox and i and j, and is thus always of size 256 + 1 + 1. This is a slight abuse of terminology, and assumes you know what you are doing. Don't use it if you can avoid to.

RETURN VALUE

Returns SHISHI_OK iff successful.
