/**
 * Computes BLAKE2b hash of a message
 * @param {import('../types.js').Input} message - Message to hash
 * @param {object} [options] - BLAKE2b options
 * @param {number} [options.dkLen=64] - Output length in bytes (default: 64)
 * @param {Uint8Array | string} [options.key] - Optional key for keyed hashing
 * @param {Uint8Array | string} [options.salt] - Optional salt for randomized hashing
 * @param {Uint8Array | string} [options.personalization] - Optional personalization string
 * @returns {Uint8Array} BLAKE2b hash of specified length
 * @property {number} outputLen - Length of hash output in bytes (64)
 * @property {number} blockLen - Length of hash block in bytes
 * @property {function(object?): import('../types.js').HashInstance} create - Creates new BLAKE2b hash instance for streaming
