Bug ID: 52457 Summary: CNG Encryption Failure (BCryptEncrypt) Product: Wine Version: 7.0 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: bcrypt Assignee: wine-bugs@winehq.org Reporter: x256@ultra.fyi Distribution: ---
Created attachment 71746 --> https://bugs.winehq.org/attachment.cgi?id=71746 Demo application (with source code)
The CNG encryption function BCryptEncrypt does not always work properly.
Please see the attached demo application. It encrypts 4 blocks (AES in CBC mode, test vector from RFC 3602): one BCryptEncrypt call encrypts the first two blocks, and a second BCryptEncrypt call encrypts the last two blocks. On Windows, all 4 blocks are encrypted correctly. On Wine, the first two blocks are encrypted correctly, but the last two blocks are incorrect.
Tested with Wine 5.0.3 and 7.0.0 (winehq-stable) on Kubuntu 21.10 (64-bit).
Thanks!
