Hello Everyone,
Hash functions play a crucial role in enhancing the security of information in various
applications. Digital Certificates are examples of how hash can be used to help make information
more secure. These hash functions are employed in the creation and verification of digital
signatures within digital certificates. The hash value of a message is encrypted with the sender’s
private key to create a digital signature [ CITATION Inv19 \l 1033 ]. Recipients can use the
sender's private key to decrypt and verify the signature, ensuring the message’s integrity and
authenticity. A digital signature is a mathematical technique that is used to validate the
authenticity and integrity of a message, software, or digital document. It consists of a small
amount of binary data, which is typically less than 256 bytes, and can be verified by any other
user to ensure that the data has not been changed since it was signed.
