AES Encryption Error (-207) After Cryptography Pack Update

VCL TMS Cryptography Pack
1

Hi,

I recently updated the Cryptography Pack used in my Delphi FMX project. After the update, I started encountering an issue with AES encryption/decryption.

In the updated version, AES operations consistently raise the error -207 during encryption/decryption.

To isolate the issue, I downgraded to the legacy version of the Cryptography Pack. With the legacy version, the same AES logic works as expected without any errors.

This leads me to believe there may be a breaking change or difference in behavior in the newer version.

I’ve attached a demo project that reproduces the issue.

here is demo project:

Hi, this is a conversion issue change between 4.x and 5.x.

Please refer to other posts on AES / Error -207 / Error -208 in the TMS Crypto support section.
