NAME
+ +
+ + setupRC4state, rc4, rc4skip, rc4back - alleged rc4 encryption
+ +
+

SYNOPSIS
+ +
+ + #include <u.h>
+ #include <libc.h>
+ #include <mp.h>
+ #include <libsec.h> +
+ + void setupRC4state(RC4state *s, uchar *seed, int slen) +
+ + void rc4(RC4state *s, uchar *data, int dlen) +
+ + void rc4skip(RC4state *s, int nbytes) +
+ + void rc4back(RC4state *s, int nbytes)
+ +
+

DESCRIPTION
+ +
+ + +
+ + This is an algorithm alleged to be Rivest’s RC4 encryption function. + It is a pseudo-random number generator with a 256 byte state and + a long cycle. The input buffer is XOR’d with the output of the + generator both to encrypt and to decrypt. The seed, entered using + setupRC4state, can be any length. The generator can + be run forward using rc4, skip over bytes using rc4skip to account + lost transmissions, or run backwards using rc4back to cover retransmitted + data. The RC4state structure keeps track of the algorithm.
