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.
