Hi,

I used crypt command, the meassage is can not encript a file
then I did $ man crypt and it is there as a function
$ cat filename|crypt > filename.cpy --> does this works, I haven't tried.

it looks like crypt command is not working as an old verion of OSS.

Why not use gpg instead?

$ gpg -c -o output-file input-file
[enter password]

Done.

Perhaps it won't encrypt a text file without a password. Not sure.

You want to encrypt a file without a PW?

You often need a key (password) for most encryption methods. Whether they're public or private.

crypt is typically used to generate an encrypted (hashed) password, not to do file encryption. As suggested, check into gpg (GnuPG).

Hi,

I'll check gpg and let you know. Thanks

I've used a program called ccrypt( not to be confused with crypt ) to encrypt files. That was then. Today, I use cryptsetup on a usb stick. All I do is insert the usb stick and a dialog box opens and prompts me for the passphrase. Then I just add the files I want to keep secured.
