and
cat encrypted.data | openssl des3 -d

Beautiful and simple – I didn’t realize this was built-in to Leopard! Thanks!

[...] Also, from this awesome tip from OS X Daily, you can quickly encrypt a file using openssl using the following (I used AES 128 in CBC mode) — it even prompts you for the encryption password (key) twice: [...]

@mchl: Just remember if you enter your password on the command line, it will be stored in plain text in your .bash_history file.

Many thanx for this information. Please note the possibility to add a password directly (it took me as a newby some hours to figure this out):

openssl des3 -salt -in file.txt -out file.des3 -k mypassword

You could ZIP it first.

mugab -

It might not be EXACTLY what you’re looking for – but I just posted the steps to make this command into a shell script. At least you can drag the file you want encrypted into a Terminal window !

Great tip OSXDaily !

If you want to protect a folder or more than one file use the disc utility, click on new image, set the space and the password.

This is a great solution. Another one would be to grab gpg for OSX and use ‘gpg -c ‘

It’d be nice if there was an easy drag and drop utility to do this that just prompts you for a password. I’m not really command line savvy and I think there’s a lot of room for error.
