Lockbox 3: Daten verschlüsseln und in PHP entschlüsseln

[amigage]

Danke für Deine Bemühung, mir zu helfen. Bitte, eines noch: folgendes habe ich noch bei StackOverflow gefunden:

Zitat:

The upshot is that you can use the TCodec component without writing single line of code to manage IV's, and you still get all the cryptographic benefits of salting (basically meaning unpredictable IV's). This is in contrast to DCPCrypt, where you either have zeroised IV's or you self-manage the IV's.

und zum Padding:

Zitat:

...
Other (such as CBC)

No padding. Termination is handled by ciphertext stealing, which is "too cool for school"! If the message is too short for ciphertext stealing (less than 2 blocks), then it automatically switches to CFB-8 bit and treat as key-streaming.

Womöglich liegt es an meinem zu kurzen Probetext?
Was ist "CFB-8 bit and treat as key-streaming"?

Besten Dank.
