How to encrypt with AES?

[rossi.ma...@gmail.com]

Hello everyone,
reading old conversations I learned that in Harbour it is possible to use AES encryption but I couldn't figure out how to do it.
Could someone please show me, step by step, what to do?
An example of use would also be helpful.

Regards.

[Takács Gábor]

I found complete working method to aes128, 192, 256 without any extra libs (crypto, Ssl, etc.), i send the link soon..

Can you post the working method here please?

I believe Victor's branch of harbour has some enhanced encryption functions that are not in the main branch of harbour.

Vicor’s branch has sha3512 func.

Hello Everyone,

Please refer to this discussion ---> https://groups.google.com/g/harbour-users/c/nVwkOKE8hAM/m/_Alv-RgNAgAJ  "What it translates to in Harbour - AES 256 (AES/ECB/PKCS7Padding)" 

I had inserted a sample code that I have been using for a few years and then I was supposed to add an example PRG and, Diego provided a better written example: EVP_CIPHER.PRG, then I didn't provide my example PRG as Diego's sample is better written and concise. 

Please feel free to ask anything related to AES Encryption and Decryption.

I have tested these with OpenSSL 3.4.0 and works perfectly. 

Best regards,

[Gábor Takács]

 under Szabó Attila's post you find link to test.
    https://8gwifi.org/CipherFunctions.jsp
 
This .zip contains full working harbour code without any internal libs (ssl, etc.)
But. This release not contain any PKCS5 etc. paddings.

I use only standard AES128 (the code contain AES192 and AES256) +  minimal coding work to added padding PKCS5/PKCS7.

Please download it and test. Let me know how you get on.
