Using GPG

If there's a reason to use encryption for messages or simple sign some files you share over untrusted services, you've to install gnupg

To make life a bit easier, I'd share some useful commandline tips:

Create a new key

To generate a new private/public key:

gpg --full-generate-key
... follow the prompt

List of available keys:

gpg -k
gpg -K

the last one is for private keys

Create a subkey

gpg --edit-key 0xMYKEY

> addkey
... follow the prompt

Export subkey (check its id by gpg -k):

gpg -a --export 0xSUBKEY

Import someones public key

gpg --import somekey.asc

Encrypt file using someones public key (for an instance mine):

gpg --encrypt -r g0tsu@dnmx.org secretfile.txt

Decrypt file someone sent to you

gpg --decrypt secretfile.txt.gpg

Public GPG Key

You can download g0tsu.asc file, or copy it as a text:
