16 | + * This code is derived from section 17.1 of Applied Cryptography, | |
17 | + * second edition, which describes a stream cipher allegedly | |
18 | + * compatible with RSA Labs "RC4" cipher (the actual description of | |
19 | + * which is a trade secret). The same algorithm is used as a stream | |
20 | + * cipher called "arcfour" in Tatu Ylonen's ssh package. | |
21 | + * | |
22 | + * Here the stream cipher has been modified always to include the time | |
23 | + * when initializing the state. That makes it impossible to | |
24 | + * regenerate the same random sequence twice, so this can't be used | |
25 | + * for encryption, but will generate good random numbers. | |
