Swift wrapper for reference C implementation of BLAKE2 hash functions.


Blake2 deploys to macOS, iOS, tvOS, watchOS and Linux. It has been tested on the latest OS releases only however, as the module uses very few platform-provided APIs, there should be very few issues with earlier versions.

Setup instructions:

  • Swift Package Manager: Add this to the dependency section of your Package.swift manifest:

    .package(url: "https://github.com/tesseract-one/Blake2.swift.git", from: "0.1.0")
  • CocoaPods: Put this in your Podfile:

    pod 'Blake2', '~> 0.1'

Usage Examples

import Blake2

let data = Data("some data for hashing".utf8)

// Simple hash api. 64 byte Blake2b hash.
let hash = try! Blake2.hash(.b2b, size: 64, data: data)
print("Hash", hash)

// Streaming hash api. 64 byte Blake2b hash.
// Create hasher object
var hasher = try! Blake2(.b2b, size: 64)
// insert data by chunks
// and then finalize hasher
let hash2 = try! hasher.finalize()
print("Hash", hash2)
