The Digital Signature Manager creates what is called a full signature which contains the digital signature itself as well as a certificate set. It follows then that a successful decryption would assert the identity of the signer since only the holder of the corresponding private key could have signed the data. Data encrypted with the private key can only be successfully decrypted with the corresponding public key. One of these numbers is your private key which you keep a secret, while the other number is your public key. Their scheme, known as the RSA public key crypto-system, is based on arithmetic algorithms using a pair of large prime numbers. The method was improved soon afterwards by R. In terms of trust, a signature that has been successfully verified can be more trustworthy than a signed and notarized piece of paper since a digital signature can detect any alterations to the signed data and a digital signature can not be forged.ĭigital signatures are based on a cryptographic technique called public key cryptography. A digital signature serves two purposes, it uniquely identifies the individual or entity that signed the data and it assures the integrity of the data that was signed.Ī digital signature can apply to an entire document or any portion of it. A digital signature is basically a big encrypted number that is associated with a piece of data. It is not a graphic representation of your handwritten signature that your plop onto an electronic page. Let me start by telling you what a digital signature is not. Ill try not to go into too much gory detail here, but you should understand some of the principles involved. In this article we will concentrate on the Digital Signature Manager though there may be some references to the other parts to fill things in. DigiSign is comprised of three parts the Digital Signature Manager and API, Drag and Drop signing in the Finder, and the DigiSign Utility.
