Webhooks are "user-defined HTTP callbacks". [2] They are usually triggered by some event, such as pushing code to a repository, [3] a new comment or a purchase, [4] a comment being posted to a blog [5] and many more use cases. [6] When that event occurs, the source site makes an HTTP request to the URL configured for the webhook.
It is called a three-pass protocol because the sender and the receiver exchange three encrypted messages. The first three-pass protocol was developed by Adi Shamir circa 1980, and is described in more detail in a later section. The basic concept of the three-pass protocol is that each party has a private encryption key and a private decryption key.
The simplest such pairwise independent hash function is defined by the random key, key = (a, b), and the MAC tag for a message m is computed as tag = (am + b) mod p, where p is prime. More generally, k -independent hashing functions provide a secure message authentication code as long as the key is used less than k times for k -ways independent ...
The Sender Rewriting Scheme (SRS) is a scheme for bypassing the Sender Policy Framework's (SPF) methods of preventing forged sender addresses. Forging a sender address is also known as email spoofing .
The reveal phase is the sender giving the key to the receiver, who uses it to open the box and verify its contents. The locked box is the commitment, and the key is the proof. In simple protocols, the commit phase consists of a single message from the sender to the receiver. This message is called the commitment.
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. [1] [2] Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions.
The test is executed using a driver that reads the keywords and executes the corresponding code. Other methodologies use an all-in-one implementation stage. Instead of separating the tasks of test design and test engineering, the test design is the test automation. Keywords, such as “edit” or “check” are created using tools in which the ...
Sliding windows are a key part of many protocols. It is a key part of the TCP protocol, which inherently allows packets to arrive out of order, and is also found in many file transfer protocols like UUCP-g and ZMODEM as a way of improving efficiency compared to non-windowed protocols like XMODEM.
