Implement AES 128 ECB
« on: April 18, 2020, 09:35:00 pm »
Hello everyone!
I need to be able to decrypt a 128 bit hexadecimal string with AES 128 ECB (Electronic Code Book)
what can be used for that?

try this component but I can't get the examples to work .. maybe because I'm new to this language and I'm not figuring out how to do it

DCPCrypt

Thank you

I don't know about your particular problem, but for use with fpc, dcpcrypt should be downloaded from this location: https://sourceforge.net/p/lazarus-ccr/dcpcrypt/ci/master/tree/
There is "Download snapshot" button on that page.

Other sources are old and not maintained.

Some info in wiki.

Our member Xor-El (short-hand for a very long name...) My Nigerian (dialects, this country has over 100 languages) is not up to date... has an excellent library here:
https://github.com/Xor-el/
Passes all tests...and is maintained...

And he is almost always available for advice.

Thanks, Thaddy, I somehow didn't know  about these libraries.

it's our igbo friend (I don't know Nigerian languages, but "igbo" means something to me since I read this wonderful book).

I second @Thaddy, Xor-el has an excellent library that I use often.
For aes ecb, here's one of the tests which shows usage
