Message Encryption

Message encryption secures data: transforming readable text into an unreadable format, accessible only with the correct key.

Message encryption protects digital communications. It converts plaintext into ciphertext using an algorithm and a key, making data unintelligible to unauthorized parties. Decryption, the reverse process, restores the original message with the correct key. This technology is fundamental to secure online interactions, from email (PGP/MIME) and messaging apps (Signal Protocol) to banking transactions (TLS/SSL). Strong encryption ensures confidentiality and integrity, safeguarding sensitive information against interception and tampering across networks.
