Which key is used for digital signature?
Hereof, which key is used to create a digital signature?
To create a digital signature, signing software -- such as an email program -- creates a one-way hash of the electronic data to be signed. The private key is then used to encrypt the hash. The encrypted hash -- along with other information, such as the hashing algorithm -- is the digital signature.
Also Know, what is public key in digital signature? A public key encryption involves a key pair: one public and one private. The sender of an electronic document uses their private key to encrypt that document; this is the digital signature. The receiver then decrypts the signature with the public key to verify that it matches the attachment.
