The Elliptic Curve Digital Signature Algorithm Flaw

A simple introduction to DSA

As you know the digital signature is used to verify :

• The document is created by the author with public key
• The message or document is not tampared

This Digital signature can be generated by any cryptographic hash function like SHA256.

We can say that Digital signatures are an asymmetrically encrypted hash of a digital message (data), It is a value that can provide a guarantee of authenticity, non-repudiation and integrity.
