Cryptographic signatures, automatic.

A drawn-on signature looks the part, but anyone with a PDF editor could’ve put it there. A digital signature is different — it’s a cryptographic seal that says “this PDF came from me and hasn’t been altered since.” pdfMachine applies one as easily as the drawn kind.

Apply with one click. Pick a digital signature you’ve already created (or make a new one) and drop it on the PDF. Looks like a stamp, behaves like a notary.
Recipients can verify it. Open the PDF in Adobe Acrobat (or any reader that supports digital signatures) and the signature shows up as valid — confirming the doc came from you and hasn’t been changed since you signed.
Auto-sign every PDF you create. Configure pdfMachine to apply your digital signature automatically to every PDF you print. Set it once, and every doc that leaves your machine is signed.

Sign once. Trust earned.

Provably yours.
