Commonly Asked Questions

What is a digital signature?

A digital signature is a cryptographic mechanism that verifies the authenticity and integrity of a document. Unlike a drawn signature, it uses public key cryptography (X.509 certificates) to prove the signer's identity.

What certificate formats are supported?

We support PKCS#12 format certificates (.pfx, .p12) which contain both your certificate and private key in a single encrypted file. These are commonly issued by certificate authorities.

Is my private key safe?

Yes! All processing happens entirely in your browser. Your certificate, private key, and PDF files never leave your device or get uploaded to any server.

Will the signature be valid in PDF readers?

Yes, the tool creates standard PKCS#7 detached signatures that are recognized by all major PDF viewers. For full validation, use a certificate from a trusted Certificate Authority.
