Description

Dipsifish is a text messenger that uses one-time pad key and XOR operation for encrypting messages. Every message encrypted with a pre-shared unique random key that is bigger than the message. The keys are generated and shared during the meeting between the two users over local peer-to-peer secure TLS connection. The standard key set contains 1000 keys. During the meeting two users can repeat the key sharing procedure many times, generating 2000 keys every time, each user gains 1000 keys for outgoing and 1000 keys for incoming messages. With the keys the users can send messages remotely over internet. After a message have been sent, the OTP key is deleted from the sender's key set, and in the same way, after receiving and decrypting the message, the key is deleted from the receiver's key set. The application doesn't require registration and login, it doesn't process or keep any user identification data, and so notification can not be sent to a user. Thus it is a user's will to launch application, check and download incoming messages.
The maximum message size is 128 characters.
A recipient has 5 days to download a message after that period the message will be deleted for security reasons .
