the OTR protocol

OTR (Off-the-Record) protocol is a method for secure instant messaging that ensures privacy. It encrypts messages so only the intended recipient can read them, making eavesdropping impossible. OTR also provides authentication, confirming the identities of the parties, and deniability, meaning messages can't be proven to be from a specific sender later on. It’s designed for private, confidential conversations over chat platforms, protecting against interception and ensuring that both parties can trust the authenticity and confidentiality of their communication.
