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]

       char * ivout[258]

       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.
