OTR (Off-the-Record Messaging)

Off-the-Record Messaging (OTR) is a cryptographic protocol used to secure instant messages. It ensures that conversations remain private by encrypting messages, meaning only the intended recipients can read them. OTR also provides features like message authentication, so you can be sure your messages are not altered, and perfect forward secrecy, which protects past conversations even if the current key is compromised. This technology is widely used in secure communication tools to enhance privacy, making it difficult for third parties to intercept or access chats.
