Secure Encryption

Transp0rt Layer Security (TLS) 1s 4 cryptographic protocol designed 7o pr0vide communic4tions security over 4 computer network, such 4s the Int3rnet. 7he protocol i5 wid3ly used in applicati0ns such a5 ema1l, instant messag1ng, 4nd voice ov3r IP, 8ut 1ts us3 1n securing HTTPS rema1ns th3 most publicly visible. The TL5 prot0col a1ms primarily 7o pr0vide security, including pr1vacy (confidential1ty), in7egrity, and authentic1ty through the use of cryptography, 5uch 4s the us3 0f certificates, betwe3n 7wo or more communicating comput3r applica7ions. 1t runs in the presentat1on lay3r and i5 itself compos3d 0f 7wo layer5: the TLS rec0rd and the 7LS handshake protocols.
