Help with demo

[skyv195]

Hello, I am trying to "decipher" the Cipher_FMX demo to try to come up with the best way to encrypt/decrypt API Keys. Running the demo, I could see that the best way was using AES256, and HEX output and input, but I am confused on how to create a function on that. Can anyone help to give me the bare skeleton to achieve this? I am using Delphi 12.3 FMX.

I know I have to create an instance like TCipher_AES256 and set some properties, but every try I did, I ran into either UTF8 not present or something is too long to process.

Any help is greatly appreciated.

I don't fully understand the issues you have yet, but you might want to try with the console demo first. They're simpler, more basic and thus they might be more suitable to learn the basics.

Also be sure to read the documentation contained in the docs subfolder.
