### `SetExternalDataDigest(DigestAlgorithm, byte[])`

Provides a digest of the data that was signed, so that the validation of the signatures can be performed without

different digest algorithms.

WARNING: if this method is used, it is the caller's responsibility to make sure that the digest provided actually
matches the original signed data.
