Last week, AES Crypt 4.1 was released for all supported platforms. This is a point released that addresses a number of non-critical bugs and improvements addressed since the release of the major 4.0 release at the end of August.

For those who might have missed it during the middle of the minor incremental release cycle, we also re-introduced support for Mac Intel-based platforms. That support was initially dropped with the major 4.0 release as we (incorrectly) assumed most people had migrated to the newer M-series processors. Now, both M-series (Apple Silicon / Arm) and Intel processors are supported. We will continue to support both until demand diminishes substantially.

Cheers!

Hello, I am using the Mac version. After downloading the new version, I cannot decrypt on version 3.0

AES Crypt is fully backward compatible, but perhaps there's a bug. I've not received any reported issues.

Does your password use any characters other than ASCII? Do you have a file you can share with me? I can at least check that the file appears to be properly formed.

If you're familiar with the command line, can you try to decrypt using the command line version with logging enabled? For example:
Replace "password" with your actual password.

The logging output will hint at where the issue is.

Also, you might want to send email to support for help, so not everything is posted in the public.

Edit: Maybe I misunderstood your question. Are you saying that version 3 cannot decrypt files from version 4? If so, that's correct. The new AES Crypt 4 uses an updated, more secure stream format that cannot be read by the old software.

That's right. A file encoded on version 4 I cannot decode on version 3.

How to deal with decoding it on iphone?
There is only one version on ios on which this also does not work

There's no solution for that. I am hopeful the author of the iPhone code will update their software. If not, this might be something we consider doing next year. It just depends on the level of support and interest.

While the mobile devices are nice to have, they're not used nearly as much as the desktop software.

Thank you. Where can I download version 3 for mac?

The legacy software is no longer published.
