FISH (cipher)

FISH (short for "Fast Information Security Hash") is a cryptographic hash function that was designed to provide a quick and efficient way to generate hash values from input data. Unlike more widely known hash functions such as SHA-1 or SHA-256, FISH is not as commonly used or recognized, but it was created with a focus on speed and security. The design of FISH emphasizes fast performance, which can be particularly beneficial in applications requiring high throughput or real-time processing.
