Digital signature
  • 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.
  • 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. Digital signatures use a standard, accepted format, called Public Key Infrastructure (PKI), to provide the highest levels of security and universal acceptance.
