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.
