encrypt/decrypt from linux console

ReshmiS · 02-09-2010, 12:42 AM

Hi,
I am presently looking into the crypto driver of Linux, i want to know is there any command from the Linux console that calls the crypto_alg.cia_encrypt , similar to "ifconfig eth0 up" of the network driver which in turn call the divers open.

In other words is there any console command to perform encryption/decryption from the Linux console or is there any other way to perform this from the console.

Thanks,
Chandran

I am not sure exactly what you mean by that, but you might want to look at programs like "mcrypt" and others, they operate from a shell with different options (see there related manpage). I myself use Mcrypt, it is very good for my limited needs (crypting a few files).

grub-md5-crypt is what I remember i used for boot time crypting of password.

if i would know what crypto_alg.cia_encrypt is i would say gpg. seems too easy.
