If you want to encrypt just one file use openssl or crypt. If you want to create encrypted container you can use crypted loopback or dm-crypt with loopback to file.

hi

use vim -x filename.

Moved: This thread is more suitable in Linux-Software and has been moved accordingly to help your question get the exposure it deserves.

The encryption supported by vim is very week. It is only intended to prevent another user from opening a plain text text file.

Here is an example of encrypting and decrypting a file using openssl:
openssl enc -cast-cbc -e -in ../enc.man -out enc.man.enc
openssl cast-cbc -d -in enc.man.enc -out enc.man

For more examples using openssl to encode files, read the "enc" man page. It lists the cyphers supported and there are a number of examples at the bottom.

I personally use ccrypt:

But if you have gpg installed you can also use that:

I put together a quick howto on encrypting files using openssl, which should be included in your "base" system install.

GnuPG is another fine choice.

gpg -c <filename> to encrypt it

gpg -d <filename>.gpg to decrypt the encrypted file :)
