WebDefinition. Cryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same ... WebA cryptographic hash function aims to guarantee a number of security properties. Most importantly that it's hard to find collisions or pre-images and that the output appears random. (There are a few more properties, and "hard" has well defined bounds in this context, but that's not important here.) WebCryptographically Secure Pseudo-Random Number Generators (CSPRNG) are designed to produce a much higher quality of randomness (more strictly, a greater amount of entropy), making them safe to use for security-sensitive functionality. littelfuse headquarters address
