The currently used algorithm is aes256. In the future you will be able to choose between algorithms, once more handlers have been implemented.

You said blockchain?

PirlChat is powered by the Pirl blockchain. Each message is a transaction recorded on the blockchain and is completely encrypted. For each conversation a new key is generated. The key is only available to the chatting parties and cannot be re-generated. The messages are only readable between the sender and the receiver and cannot be decrypted by any other parties.
