RC4C cipher, it's RC4 extension with two S-boxes on key and IV, and with 3 scrambling phases.
You can also install rc4c by using Bower.
bower install rc4c-js
You can encrypt / decrypt message by single call rc4c(key, iv, str), or create object, then call setup-function and series of process calls.
let c = new rc4c() // create cipher instance
c.setup("some-key", "some-iv") // setup key and IV for encryption
let s = "" // temporary storage
s += c.process("abcd") // add 1 chunk
s += c.process("1234") // add 2 chunk
console.log(s) // display encrypted result
s = rc4c("some-key", "some-iv", s) // decrypt storage by single explicit call
console.log(s) // display decrypted originalAt output you can see:
.bfD�Er
abcd1234
