update(

input: BlobOrStringOrBuffer,

inputEncoding?: Encoding

): CryptoHasher;

class CryptoHasher

Hardware-accelerated cryptographic hash functions

Used for crypto.createHash()

readonly algorithm: SupportedCryptoAlgorithms
The algorithm chosen to hash the data
readonly byteLength: number
The length of the output hash in bytes
readonly static algorithms: SupportedCryptoAlgorithms[]
List of supported hash algorithms
These are hardware accelerated with BoringSSL
copy(): CryptoHasher;
Perform a deep copy of the hasher
digest(
encoding: DigestEncoding
): string;
Finalize the hash. Resets the CryptoHasher so it can be reused.
@param encoding
DigestEncoding to return the hash in
digest(): Buffer;
Finalize the hash and return a Buffer
digest(
hashInto: TypedArray
): TypedArray;
Finalize the hash
@param hashInto
TypedArray to write the hash into. Faster than creating a new one each time
