Hi!

I have some questions about RC4 encryption.

What length should I choose for RC4 key?

Is longer key better/safer?

What is your recommendation? What max RC4 key size the extension supports?

If the key is too long, can that significantly affect encryption/decription time?

Can RC4 key contain any special characters? If yes, which ones?

Thanks a lot!

hi! 

Looking at your code, I think you are stretching the key anyway to 2048 bits, is that correct? 

In that case I can set right off my key to be 2048 bits (256 characters), right?

thx
