| 6 | 1 | johu | |
| 7 | 3 | johu | Blowfish can be used to encrypt messages between 2 persons in query, messages in channel and the topic. In Quassel all messages will be de-/encrypted on core. So it is *highly recommend* to *[[Client-Core_SSL_support|setup SSL]]* in case of you are not running monolithic client. |

| 24 | 4 | johu | |
| 25 | 4 | johu | Blowfish support for Quassel depends on *"QCA":http://delta.affinix.com/qca/* (Qt Cryptographic Architecture) library. It is needed to compile your core/monolithic client with crypt compile option. |

| 32 | 6 | johu | |
| 33 | 6 | johu | * If Quassel crashes (like #1045) when tries to send a message to a <nick|channel> where a blowfish encryption key has been set with _<code>/setkey <nick|channel> <key></code>_, you have to install *"qca-ossl":http://delta.affinix.com/qca/*. |
