| 5 | OTR (or Off-the-Record) Messaging allows you to have private conversations over instant messaging by providing: |
||
| 6 | |||
| 7 | Encryption |
||
| 8 | No one else can read your instant messages. |
||
| 9 | Authentication |
||
| 10 | You are assured the correspondent is who you think it is. |
||
| 11 | Deniability |
||
| 12 | 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. |
||
| 13 | Perfect forward secrecy |
||
| 14 | If you lose control of your private keys, no previous conversation is compromised. |
