sign_external Method

Signs the document using an external signing facility.

Syntax

def sign_external() -> None: ...

Remarks

Call this method to delegate the low-level signing operation to an external, remote, or custom signing engine. This method is useful if the signature has to be made by a device accessible through a custom or non-standard signing interface.

When all preparations are done and hash is computed, the class fires on_external_sign event which allows to pass the hash value for signing.
