Class Blake2b

StaticcomputeHash

• computeHash(data: Uint8Array, hashLength: number): Uint8Array

• Computes a BLAKE2b hash of the given data with the specified hash length.

  This method takes arbitrary binary data and computes its BLAKE2b hash with the specified output length. BLAKE2b supports output lengths from 1 to 64 bytes.

  Parameters

  • data: Uint8Array

    The input data to be hashed. This is a binary array representing the data.
  • hashLength: number

    The desired length of the resulting hash in bytes. Valid values are 1 to 64 bytes.

  Returns Uint8Array

  • The computed BLAKE2b hash as a binary array.

  Throws

  • Throws an error if the hashing operation fails.

  Example

  const data = new TextEncoder().encode("Hello, World!");
  const hashLength = 32; // 256-bit hash
  const hash = Blake2b.computeHash(data, hashLength);
  console.log("BLAKE2b Hash:", hash);
