Why do you think so?

BTW, I keep an eye on on IsTrueCryptAuditedYet and saw this yesterday:

https://www.indiegogo.com/projects/the-truecrypt-audit#activity wrote:
We are pleased to announce that Phase I of the audit is complete. 11 vulnerabilities were found, all rated Low to Medium severity. To date, we have found no 0-Day critical vulnerabilities or "backdoors" (intentional or otherwise) in the code. In Phase II, we will conduct a formal cryptanalysis, as well as examine the OSX and Linux ports.

Well, not so bad, after all. Wink

Greetings!

I thought dm-crypt would be a sufficient 2nd choice. Looks like you're concerned over lack of support. Well, dm-crypt seems OK on NT or newer, and Mobile (W8?) Windows. Always Linux. But Encrypted A within Encrypted B shows up as no. hmmmm...

There are plenty of alternatives to Truecrypt. I used Axcrypt a few years ago and it seemed to work well on individual files (Windows). There are a bunch of other free programs and scripts, as well. The full version of Adobe Acrobat has encryption for PDF's, not sure about Adobe Reader. Lots of others. The version of Puppy that I'm using has Bcrypt in the menu, though I haven't tried it. There are also bash scripts you can use.

One of the issues that I tend to have is that if I'm encrypting to send over to someone else, they need the same program on their side to decrypt. That can be a hassle.

On Windows a self-extracting encryped archive is possible,
i.e. the decryption software is included with the file (an .exe) you send, example attached , ( password is PUPPY ).

It's also possible to create a self-decrypting html webpage, and email that webpage to someone,
where they can read it in their browser if it has JavaScript enabled , ( and if they have the password, ideally sent via another channel ).

Well, I downloaded your attachment and then realized it was an exe for Windows. LOL Running 3 Linux boxes so it wasn't very helpful. Any self extracting things for Puppy (cross platform type stuff)?

Now, I've heard that Truecrypt has no back doors and further, you can encrypt inside an encryption and so on. Pretty crazy! I play around with some scripts and things but they're probably amateur hour compared to Truecrypt. What make you think it's not safe?

You can normally unpack self-extracting *.exe created by 7zip (or rar) on Linux box, just use 7z itself:
Code:
7z x somarchive.exe

The only difference between somearchive.7z and somearchive.exe is PE32 executable prepended to the latter, which (under Win) reads and unpacks the rest of a file, but when you use 7z directly, the "ugly" part will be skipped.

Also, if you have full version of p7zip installed (you can grab it here: http://pkgs.org/search/p7zip), which contains the necessary 7zCon.sfx module, you can create Linux-specific self-extracting 7z archives - in this case instead of PE32 exec, an ELF exec will be prepended (no GUI, CLI only), eg.:
Code:
7z -sfx7zCon.sfx a somearchive.sfx /path/to/file/or/dir

The webpage attached is cross-platform encryption, just requires a browser with JavaScript eneabled.

The password, aka "Key", is PUPPY , then click on "decrypt" at the very bottom of the page , then look in the big green box.

It's an adequate method for sending/storing passwords , but too slow for large amounts of data.
