Depends if you have a BBC micro computer with an LCD monitor (generate your plain text securely) and a hardware encryption/decryption controller with your own encryption/decryption encoder/decoder algorithm on a PICchip micro controller box with an RS432 interface (talks to the BBC micro) to a removable USB flash memory (encrypted files stored on a flash memory card such as an SD card).
You can then send your encrypted files via VPN tunnel or email attachment or upload to FTP server, digital radio modem, direct PSTN modem, infra-red port on a Ericsson SH888 GSM cellular phone etc.
You can even use a DOS program to embed into the noise floor the encryption data of a lossless music file or picture file such as a BMP for hiding in plain sight.
That should keep the NSA on its toes.

Looks like this new group named CipherShed has taken on maintaining and developing a fork of Truecrypt. They seem a bit more organized then the team at TCnext who are already appearing to be suffering from some infighting.

Hopefully CipherShed takes the lead on this. I am not a computer geek by any means but the world of cryptography is one area I enjoy reading and learning about so I will be following this development close.

TrueCrypt helped a lot of people solve a serious security problem. I'm happy to see that there are community-based development efforts to not let it die. I will also be following this closely.

FWIW, I've found several other methods to use TrueCrypt containers as its popularity sort of made it become an unofficial standard.

I'm not too concerned about the "may be insecure" message as that is standard text in the IT risk world. Words like may, shall, must are key in risk policy and standards and the reality is that any software may be insecure.

From a cryptoanalysis point of view, there are two means to attack the enemies cryptosystems.

1. break the system through a weakness

2. convince the enemy that you already have broken the system when you can't find a weakness in hopes that they switch to a weaker system you can break.

As far as I am aware, we have absolutely NO information which one of the two applies.
