kotlinx-murmurhash

Kotlin Multiplatform (KMP) library for MurmurHash, a non-cryptographic hash function for general hash-based lookup focused on simplicity and performance.

Usage

Add the dependency in build.gradle.kts:

kotlin {
    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation("com.goncalossilva:murmurhash:<version>")
            }
        }
    }
}

Use the provided MurmurHash* classes and hash* hashing functions.

Example

MurmurHash3().hash32x86(string.encodeToByteArray())

Contributing

Pull requests are welcome! See MurmurHash3Test for an example of how to leverage hashes computed by the canonical C++ implementation for testing.

Feel free to contribute earlier versions, such as MurmurHash2 and MurmurHash1.

Acknowledgements

Testing using a wordlist and pre-computed hashes of the canonical C++ implementation is inspired by @sangupta's murmur Java implementation.
