Secure Sockets Layer uses encryption based security to protect data. It ensures that the data is protected and authentic while it travels the internet. It is between the application and transport layers. It is seen as the parent of TLS encryption protocols, which replaced SSL due to security flaws.
Transport Layer Security uses an encrypted tunnel between connections to protect digital communication. Such as client server communication between browsers and web applications. It relies on a pseudorandom functions to create a master secret which acts as a key and derives encryption.
Secure HyperText Transfer Protocol works at the application lawyer to ensure secure connections and communications over the web. Its job is to protect online transitions like forms, database submissions, and virtual communication through authentication processes. It encrypts and ensures data integrity by digital signing mechanisms on a message to message basis rather than the full session.
Secure Electronic Transaction was created for the sole purpose of protecting financial transactions from a credit card to the internet. It secures confidentiality through a communication channel between the participants and ensures confidentiality for sensitive information. Additionally, it allows for authentication of identities for further trust between participants.
Privacy-Enhanced Mail was created to provide protection for emails. It works by using cryptographic encryption to lock the data that is being transmitted in the email to ensure its confidentiality. It denies giving the sender access to cancel the delivery.
Pretty Good Privacy is a well used cryptography tool that allows for communication and storage data to be safely contained without unauthorized access. Its widely used for personal and professional occasions due to its universal trust. It is up to date with the latest security requirements for communication and allows for full transparency by providing the source code and documentation.
