func_rc4($data,$key) : Encryption algorithms issue.

[arindel 0]

Like to learn about encryption. So I saw this on a web so I wanted to learn how to use different methods in encryption. Like for instance I wonna change from rc4 to xor, rinjadael, serpent,xxtea, and the rest.

I wanted to ask, will the opcode remain the same while I just change the functions or do I have to change some figures in the opcodes as well.

Do I change like this for example

func_rc4($data,$key) (rc4) to rinjadael

func_rinjadael($data,$key)

Kindly clarify me.
