What does a digital signature contain?
Electronic signatures—also called e-signatures—are any sound, symbol, or process that shows the intent to sign something. This could be a scan of your hand-written signature, a stamp, or a recorded verbal confirmation. An electronic signature could even be your typed name on the signature line of a document.
How do I get a Class 2 digital signature?

How is a digital signature sent to the recipient?
Once completed, the message or digital document is digitally signed and sent to the recipient. The recipient then generates their own hash of the message or digital document and decrypts the sender’s hash (included in the original message) using the sender’s public key.
How are digital signatures similar to electronic fingerprints?
Digital signatures are like electronic “fingerprints.” 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.
How is integrity ensured in a digital signature?
Ensure integrity by creating a digital signature of the message using the sender’s private key. This is done by hashing the message and encrypting the hash value with their private key. By doing this, any changes to the message will result in a different hash value.
How is the hash of a digital signature created?
The digital signature process begins with creating a cryptographic hash of the message. This hash value is also known as a “digital fingerprint” and is a unique value. The digital fingerprint is then encrypted with the sender’s private key, and the resulting value is appended to the message.
