We have already seen that a digital signature is used to verify integrity, authenticity, and non-repudiation. On the contrary, if the two hashes do not match, the data has been tampered with, hence considered invalid. If the decrypted hash matches with the second hash, it shows that the data has not been altered, and it is valid. This allows the other parties to authenticate the data’s integrity via the signatory’s public key to decode/decrypt the hash. The resulting encrypted data is what is usually called the digital signature.Īny alteration to the data will result in an incompatible or different value. The mathematical algorithm creates data that matches the signed doc, called a hash, and encrypts the said data. When a signer executes the document electronically, the signature is created via the signer’s private key.
PKI usually requires the provider to employ a mathematical algorithm to generate two keys: a private key and a public key. Digital signature solution providers, like Foxit eSign, follow a specific protocol, known as PKI. How digital signatures workĭigital signatures, like wet-ink signatures, are unique to each signatory. It can be used to sign a range of file types, like documents, videos, music, sound, etc., making it more flexible and versatile than the traditional wet-ink signature. What’s more, a digital signature is legal. This form of e-signature (simple) cannot attribute the signature to a specific signatory thus, it does not have similar features as a digital signature. A simple e-sign would be, for example, clicking on “accept” on an electronic contract or entering a Personal Identification Number (PIN) at a cash machine.
In other words, a digital signature is a vital part of the qualified and advanced e-signature, but not of the basic/simple e-signature. Integrity – that the message/document has not been altered or tampered with since it was sent.Non-repudiation – the sender cannot refute or deny that they sent the document/message.Authentication- that the sender of the document/message is real.It usually applies cryptographic measures to a document or message, to prove the following to the document’s recipient: Briefly, what is a digital signature?Ī digital signature is an electronic stamp used to validate the integrity and authenticity of a digital document.
What is used to create a digital signature how to#
Even worse, getting a document that needed multiple signatures could take weeks, especially if the signing parties were in different locations.Įntered digital signature solutions like Foxit eSign, and that painstaking process was boiled down to mere minutes.īefore we dig deep on how to make an electronic signature using Foxit eSign, let us first take a closer look at what this technology entails. If the document was sent via email, the signing party would print, sign, scan, and then email it back to the original sender. In the past, if a document required a signature, someone had to physically carry or mail the document to the other party. However, do you know how to make a digital signature in a word doc? These modern advances allow workflow automation, which improves efficiency, slashes business costs, promotes transparency, and reduces errors. The majority of business people and organizations have moved away from paper-based contracts and embraced digital documents and digital signatures.
