method Sign.prototype.sign

Usage in Deno

KeyLike
| SignKeyObjectInput
| SignPrivateKeyInput
): Buffer

Calculates the signature on all the data passed through using either sign.update() or sign.write().

If privateKey is not a KeyObject, this function behaves as ifprivateKey had been passed to createPrivateKey. If it is an object, the following additional properties can be passed:

If outputEncoding is provided a string is returned; otherwise a Buffer is returned.

The Sign object can not be again used after sign.sign() method has been called. Multiple calls to sign.sign() will result in an error being thrown.
