Digital signatures work through public key cryptography's two mutually authenticating cryptographic keys. For encryption and decryption, the person who creates the digital signature uses a private key to encrypt signature-related data. The only way to decrypt that data is with the signer's public key.

Digital signature uses a digital certificate from a trust service provider (TSP), such as a certificate authority (CA), to authenticate a signer's identity. The digital certificates demonstrate proof of signing by binding the digital certificate associated with each signature to the document using encryption.

The most common example is a wet signature scanned by an electronic device and then inserted into a document. Another example of a simple digital signature is the email signature that we often add at the end of the email, and check the terms and conditions box in the software installation process.

A digital signature is an electronic, encrypted, stamp of authentication on digital information such as email messages, macros, or electronic documents. A signature confirms that the information originated from the signer and has not been altered. The following is an example of a signature line. Top of Page.

Digital signatures are like electronic ?fingerprints.? They are a specific type of electronic signature (e-signature). In the form of a coded message, the digital signature securely associates a signer with a document in a recorded transaction.

The process of verification of digital signatures requires a digital signature certificate (DSC) issued by the Certifying Authority (CA) accompanied by their Certificate Revocation List (CRL) & the signer's public key.
