shishi_arcfour - API function

       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.

       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.
