Re: AES Crypt Error message: Message has been altered and shou

Oh, I can definitely fake a tampered file. I tested that rather extensively when writing AES Crypt, after all. Guarding against that is why there is an HMAC. Sadly, there is a bug in the logic, though, that I did fail to find. There is one octet near the end of the file called the "modulo"...

Re: AES Crypt Error message: Message has been altered and shou

I checked the source and, indeed, the call to remove the file happens only after the decrypt_stream() call is made to decrypt the file and an error value is returned. So, the approach I suggested would work to get around the unwanted delete on failure. I'd suggest that as opposed to changing the cod...

Re: AES Crypt Error message: Message has been altered and shou

Sorry you had that issue. The simplest solution to this is to use the command line version and direct output to stdout (-) and direct it to a file. For example: aescrypt -d -p foo -o - file.doc.aes >file.doc I didn't check the code to see if that last block is written, but I can look. If you want to...

Re: Cannot load AES Crypt

I have both a business and personal OneDrive. I use my personal OneDrive to share files with people since the business account shares user or domain information as a part of the link, if I recall. I did not like that. This is something I wish Microsoft would change, but I'll readily admit I haven't ...

Re: Cannot load AES Crypt

I appreciate you doing that, because I had never tried it, myself. Indeed, the context menu does not appear for files out in the cloud. I forget how I wrote that code, but I do recall making an effort to only present that menu for "regular" files, so certain types of "links" woul...

Re: Cannot load AES Crypt

Once you run the .msi file, you're set. Just right-click on a file you want to encrypt and you should see an option that says "AES Encrypt" or "AES Decrypt". Choose that option and a box will appear prompting you for a password. Once you provide a password, it will do it's job an...

Re: Bruteforcer tool

@radium, Here ya go: http://www.aescrypt.com/download/v3/linux/aescrack.tgz Have a look at decrypt.c, and specifically decrypt_optimized(). You can integrate that logic with the generation of passwords you're using to see if a v1 or greater file can be decrypted using the password you try. The v0 fi...

Re: Aescryt for MAC don't work on Big Sur

Did you put the lock icon on the dock as explained in the user guide, or are you trying to run it directly? It cannot be run directly. It works only by dragging/dropping files.
