I personally use DiskCryptor, but I am not super up-to-date on the best programs for encryption/decryption.

DiskCryptor does the job for me. Easy to use, open source.

I am not sure you actually read what the OP asked for.He/She talked about Linux.

DiskCryptor is only available for Windows(0)

To OP,you may check out LUKS(Linux Unified Key Setup)(1).

Or I read the question, and mistakenly assumed DiskCryptor worked with Linux without confirming.

Oops.
