Encrypt every file in the current directory with 256-bit AES, retaining the original.

for f in * ; do [ -f $f ] && openssl enc -aes-256-cbc -salt -in $f -out $f.enc -pass file:/tmp/password-file ; done
The password is stored in the password file, which obviously must be kept secure, encrypted later with gpg, deleted, or whatever you prefer. To decrypt: openssl enc -d -aes-256-cbc -salt -in filename.enc -out filename -pass file:/path/to/password-file Alternative ciphers can be used, of course.

What Others Think

I usually create a tar file of a directory and encrypt that. If you plan to keep the files together as a group, its much easier.

I just used it to encrypt a collection of compressed tar r files. They must be compressed first, sisince encrypted data can't be compressed.
