Frequently Asked Questions
Do I need digital signatures or are e-signatures enough?
For most business documents, standard e-signatures are legally sufficient and easier to use. Digital signatures are recommended for high-security needs, regulated industries, or when recipients require cryptographic verification.
What's the difference between digital signatures and e-signatures?
Digital signatures use PKI cryptography with certificates to mathematically verify authenticity. E-signatures are any electronic indication of agreement. Digital signatures are a subset of e-signatures with higher security.
Are digital signatures more legally valid?
Both are legally valid under ESIGN and UETA. Digital signatures provide stronger evidence and are required in some regulated contexts, but standard e-signatures are sufficient for most business uses.
How do I verify a digital signature?
Most document readers (Adobe Acrobat, etc.) automatically verify digital signatures and show validation status. The verification checks that the document hasn't been altered and the certificate is valid.
