encrypting data from the command line

[chr15b]

not really a batch file question as such, but.. has anyone had the need to encrypt data from the command line using public/private keys or similar?

The issue is the password being in the batch file, i need to find some way of encrypting some data from the command line using a password (stored in the batch file) that cannot be used to decrypt it.

I found via google some discussions of the functionality of it being in 7zip - but the trail went cold

any ideas or suggestions gratefully received.

Thanks

Found a solution, gpg, it allows you to encrypt the file(s) just by specifying a name - to decrypt them you have to provide the key for the certificate.

Best of all, it's free
