§
new Blake2b(key?: Uint8Array, digestLength?: number)
[src]Throws RangeError if either the key or digest length are
larger than 64 bytes, or if the digest length is negative.
@param key
Hash key. Must be between 0-64 bytes.
@param digestLength
Length of digest in bytes, defaulting to 32. Must be between 0-64 bytes.
§Properties
§Methods
§
digest(): Uint8Array
[src]Finalizes the state and produces a digest. Throws if the hash function is already finalized.
§
update(input: Uint8Array): this
[src]Feeds input into the hash function in 128 byte blocks. Throws if the hash function is finalized.
@param input
Input bytes
