Hi Jakob, Unfortunately encrypting the ciper again does not decrypt it. To decrypt, you need to provide generated keys in inverted order. That's what I want to achieve.
I know about "on the fly" functionality, but when you use it, it encrypts/decrypts data on each transmission and I want to encrypt it once, send it through the network and decrypt it on receiver. 2011/6/2 Jakob Bieling <[email protected]>: > Hi, > > try "encryting" the cipher text again.
