HawkOpen accepts either a drawn signature or a typed name of at least two characters. The code from the email shows only that the person had access to that mailbox; it does not establish their identity or their authority to sign on behalf of a company. The evidence report records which document was signed and when, with HawkOpen’s Ed25519 signature on the record.
Where the law requires written form, check whether and how an electronic form can meet that requirement in your country: in Germany, for example, a qualified signature unless a provision excludes it; in Spain, an electronic medium under the LSSI, with exceptions. When in doubt, ask a lawyer. The HawkOpen e-signature is a preview version until external file scanning is switched on.
