Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP). It uses encryption for secure communication over a computer network, and is widely used on the Internet. [1] [2] In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or, formerly, Secure Sockets Layer (SSL).
Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network, such as the Internet.The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
SSL (Secure Sockets Layer) is an industry standard for encrypting private data sent over the Internet to help protect your account and information. Learn what SSL is and how we use it to protect your account.
It is widely used by Internet servers, including the majority of HTTPS websites. OpenSSL contains an open-source implementation of the SSL and TLS protocols. The core library, written in the C programming language, implements basic cryptographic functions and provides various utility functions. Wrappers allowing the use of the OpenSSL library ...
Multiple encryption is the process of encrypting an already encrypted message one or more times, either using the same or a different algorithm. It is also known as cascade encryption, cascade ciphering, multiple encryption, and superencipherment. Superencryption refers to the outer-level encryption of a multiple encryption.
Newer variants of TeslaCrypt were not focused on computer games alone but also encrypted Word, PDF, JPEG and other files. In all cases, the victim would then be prompted to pay a ransom of $500 worth of bitcoins in order to obtain the key to decrypt the files. [4] [7]
Encrypted Client Hello (ECH) is a TLS 1.3 protocol extension that enables encryption of the whole Client Hello message, which is sent during the early stage of TLS 1.3 negotiation. [10] ECH encrypts the payload with a public key that the relying party (a web browser) needs to know in advance, which means ECH is most effective with large CDNs ...
ACME logo. The Automatic Certificate Management Environment (ACME) protocol is a communications protocol for automating interactions between certificate authorities and their users' servers, allowing the automated deployment of public key infrastructure at very low cost.
