PGP For All

PGP ni direka oleh Philip Zemmermann pada awal tahun 1990. PGP penting utk mengesahkan identiti kita dan mengesahkan perkara2 lain mcm dokumen, pakej, surat dll. Ok la disebabkan PGP dh gune IDEA dan IDEA ni telah dipatenkan maka kite tak leh gune pgp yg asal. Aku sages korg gune GnuPGP sbb:
GnuPG is a complete and free replacement for PGP. Because it does not use the patented IDEA algorithm, it can be used without any restrictions. GnuPG is a RFC2440 (OpenPGP) compliant application.

Ok cara nk install gnupg ni kt gentoo senang je. Memula ko taip ni:
# emerge -va gnupg
pastu tekan 'y' utk install pakej ni

Bila dh install gnupg. Maka bole la korg generate key utk identiti korg. Koman dia mudah je, taip ni:
#gpg --gen-key
pastu pilih no 1 utk DSA and ElGamal,
amik keysize 1024. atau korg bole letak 2048 utk lebih sekuriti,
pilih 0 utk valid forever. maknenye key takkan expired,
pastu masukkan nama, e-mel dan komen,
dan masukkan bende penting iaitu passphrase. passphrase ni mcm password.

Ok skang korg dh pgp sendiri. utk upload ke pgp server, korg boleh upload dlm btk binari atau ascii armored. utk dptkn dlm btk binari taip koman nih:
# gpg --output identiti.gpg --export emel@korang.com

atau dlm format ascii armor, taip ni:
# gpg --output identiti.asc --armor --export emel@korang.com

sebelum upload ke pgp server, tgk dulu hex code utk pgp key korg, taip ni utk tgk pgp key in hex code:
# gpg --edit-key emel@korang.com
tgk kt bhgian pub kt situ ade hex code nye (perkataan dlm bold)
pub 1024D/5E82CF73 created: 2006-02-22 expires: never usage: CS
Command> quit

then korg leh upload ke pgp server. aku sages letak kt pgp.mit.edu sbb kebykan pgp key ade kt situ. jgn takut sbb nnt pgp server akan saling forward pgp key korg ke pgp server yg lain.
# gpg --keyserver pgp.mit.edu --send-key 0x5E82CF73

lepas dh upload. bole la korg blagak sket dh ade pgp key ngan attach pgp signature kt emel korg. byk emel client yg sapot pgp nih mcm thunderbird, outlook dan lain-lain lagi. Enjoy!

Mood: ^_^ (cayala!)
