VeraCrypt being the only real alternative to TrueCrypt, I also mentioned that I was still using TrueCrypt on my Linux VPS private email server. Well, after writing that post I wanted to see if VeraCrypt could mount a TrueCrypt volume, and it turns out it can!

According to VeraCrypt, you can convert an existing TrueCrypt volume by performing any of these functions, but you must select TrueCrypt mode to do it:
- Change Volume Password

- Remove all key files
I haven't tried it yet, but changing the password and or key files to convert it to a VeraCrypt volume via the terminal version should be as simple as running the following on your original TrueCrypt volume while it's dismounted:
Not wanting to risk corrupting all of my emails, I think I will hold off on doing that until I'm ready to change my password again, and I'll make sure I have a good backup first! Still though, even if it doesn't work, at least I can mount that volume now with VeraCrypt!
Edit: I've verified that the above command does in fact work to change the password and upgrade your TrueCrypt volume to the new VeraCrypt format via the cli/terminal! If you were wondering how to upgrade a TrueCrypt voume to a VeraCrypt volume via command line, there you go!
