Blazor got admitted as an official open-source project by Microsoft, and in 2018, as part of .NET Core 3.1, Blazor Server was released to the public. [citation needed] It enabled server-driven interactive web app that updates the client browser via WebSockets. Shortly thereafter, Blazor WebAssembly was released.
The Symbolic Stream Generator (or SSG) is a software productivity aid by Unisys for their mainframe computers of the former UNIVAC 1100/2200 series. SSG is used to generate RUN-Streams (corresponding to IBM's Job Control Language ), apply and administer symbolic changes to program sources as a form of version control , and for many other purposes.
Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). A sender encrypts data with the receiver's public key; only the holder of the private key can ...
In cryptography, a keystream is a stream of random or pseudorandom characters that are combined with a plaintext message to produce an encrypted message (the ciphertext).. The "characters" in the keystream can be bits, bytes, numbers or actual characters like A-Z depending on the usage case.
Microsoft Learn is a library of technical documentation and training for end users, developers, and IT professionals who work with Microsoft products. Microsoft Learn was introduced in September 2018. [1]
Stream ciphers are vulnerable to attack if the same key is used twice (depth of two) or more. Say we send messages A and B of the same length, both encrypted using same key, K. The stream cipher produces a string of bits C(K) the same length as the messages. The encrypted versions of the messages then are: E(A) = A xor C
The stream cipher key or seed should be changeable in a way that can be audited and derived from a trustworthy source, e.g. dice throws. The Fortuna random number generator is an example of an algorithm which uses this mechanism. Generate passwords and passphrases using a true random source.
A public key infrastructure (PKI) is a system for the creation, storage, and distribution of digital certificates, which are used to verify that a particular public key belongs to a certain entity. The PKI creates digital certificates that map public keys to entities, securely stores these certificates in a central repository and revokes them ...
