SipHash
A pure Swift implementation of the SipHash-2-4 cryptographic hashing algorithm for secure hashing in Swift.
What is SipHash?
SipHash is a pure Swift implementation of the SipHash-2-4 cryptographic hashing algorithm, designed for secure and efficient hashing of short messages. It provides a `SipHashable` protocol and direct hasher usage to simplify hash implementation in Swift, though it is now obsoleted by Swift 4.2's standard `Hasher`.
Swift developers targeting versions before Swift 4.2 who need a secure, standardized hashing algorithm for data structures like sets and dictionary keys, or for network traffic authentication.
Developers choose SipHash for its implementation of a well-regarded cryptographic hash algorithm in pure Swift, offering security against collision attacks and a simpler API than custom hash functions, though it is no longer recommended for modern Swift code.
