ahash

ahash is a non-cryptographic hash function designed for speed and good distribution. It is often used in hash tables and other data structures where fast lookups are important. The algorithm works by combining parts of the input data in a series of bitwise operations, including XOR and multiplication. This process aims to produce a hash value that is unique for different inputs, minimizing collisions.

The implementation of ahash is typically straightforward, making it easy to integrate into various software projects. It's known for its simplicity and efficiency, particularly on modern processor architectures that can perform these bitwise operations quickly. While not suitable for security-sensitive applications like password hashing, its performance characteristics make it a popular choice for general-purpose hashing needs. The output of ahash is usually a 32-bit or 64-bit integer. Its design prioritizes speed over absolute collision resistance, which is a common trade-off in non-cryptographic hashing.
