The \fIout\fP 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. .SH "RETURN VALUE" Returns SHISHI_OK iff successful. .SH "REPORTING BUGS" Report bugs to .
