Perintah Penting
$ gpg --gen-key $ gpg -gen-revoke nobody@york.ac.uk $ gpg -armour --export nobody@york.ac.uk $ gpg --keyserver certserver.pgp.com --send nobody@york.ac.uk
Encrypt Decrypt Dokumen
$ gpg --output doc.gpg --encrypt --recipient blake@cyb.org doc $ gpg --output doc --decrypt doc.gpg
Atau menggunakan Symetric Key
$ gpg --output doc.gpg --symmetric doc
Membuat Tanda Tangan & Verifikasi Tanda Tangan
$ gpg --output doc.sig --sign doc $ gpg --output doc --decrypt doc.sig
Supaya menjadi tanda tangan berbentuk ASCII text, istilahnya ASCII Armour
$ gpg --clearsign doc
Membuat Key baru
Gunakan perintah gpg --gen-key
$ gpg --gen-key
Outputnya ..
