What is the most secure way to encrypt a file with sensitive data?

Can anyone recommend me a way to encode files of sensitive data so that no one can crack them? I will be the only who knows the password.

I am thinking of using GPG but I know next to nothing about security. A开发者_JAVA技巧ny suggestions which algorithm from GPG to use for encryption?

Thanks, Boda Cydo.

Put your data into a Thumb/USB drive, and use TrueCrypt

GPG is fine. AES is a good choice as an algorithm, and since you are encrypting them only for your own use, symmetric encryption is fine:

gpg --symmetric --cipher-algo AES < infile > outfile

It will prompt you for a passphrase. To decrypt:

gpg < infile > outfile
