Digital signature of PDF document

Digital signature application is designed to quickly and easily add a digital signature to your PDF document. Note, please do not confuse a digital signature with a digital certificate and a signature on a document page in the form of a stamp. The digital certificate signing mechanism means that if your PDF document is changed, the signature will become irrelevant and the document will not be verified when verifying the digital signature with a public key. This application now supports the two most popular certificate variants, the .P12 and .PFX certificates. To add a digital signature, you need to select one or more PDF documents, select a certificate to sign, and specify a password for the certificate. Your files will be securely sent to the server and processed, after which your certificates will be deleted from our servers, and the signed document will be available for download within 24 hours. You can also use the application to add a digital signature to verify that your document is signed correctly. To do this, simply specify the certificate with which the document was signed.
