otr itu adalah: “a cryptographic protocol that provides strong encryption for instant messaging conversations.” – baca lengkap disini

adapun fungsi dari otr adalah:

Off-the-Record (OTR) Messaging allows you to have private conversations over instant messaging by providing:

Encryption

No one else can read your instant messages.

Authentication

You are assured the correspondent is who you think it is.

Deniability

The messages you send do not have digital signatures that are checkable by a third party. Anyone can forge messages after a conversation to make them look like they came from you. However, during a conversation, your correspondent is assured the messages he sees are authentic and unmodified.

Perfect forward secrecy

If you lose control of your private keys, no previous conversation is compromised.

otr bisa digunakan untuk:
Adium+Adium X
Trillian
pidgin
gaim

gw baru nyoba untuk install otr di adium + pidgin. tapi dari testing kemaren gw (pake adium di mac) blon bisa untuk tuker enkripsi key ama kitsuensha (pake pidgin di windows) … tapi kalo antar sesama jenis (adium+otr proxy ke adium+otr proxy … atau pidgin+otr ke pidgin+otr) sih bisa … mungkin karena kalo si adium pake plugin otr yg proxy kayanya (sotai mode: on) … nanti ada tanda gembok ama fingerprint id kalo dah berhasil tukeran encrypt keynya

lha untuk YM mana? hahahaha … hari gini masih pake YM???

peace,
