WebCryptography is the study of securing communications from outside observers. Encryption algorithms take the original message, or plaintext, and converts it into ciphertext, which is not understandable. The key allows the user to decrypt the message, thus ensuring on they can read the message. WebSSL, or Secure Sockets Layer, is an encryption -based Internet security protocol. It was first developed by Netscape in 1995 for the purpose of ensuring privacy, authentication, and data integrity in Internet communications.
