WebA 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 WebJan 7, 2024 · Asymmetric encryption is used mainly to encrypt and decrypt session keys and digital signatures. Asymmetric encryption uses public key encryption algorithms. Public key algorithms use two different keys: a public key and a private key. The private key member of the pair must be kept private and secure.
