What is Digital Signature?
A digital signature is a mathematical scheme that undeniably identifies the sender of the electronic document and attests to the non-alterability of the information it contains.
It can be compared to a human’s fingerprint, which is unique and can help verify the true identity of a person.
In order to create a digital signature and make sure that information is absolutely safe from hackers, blockchain uses advanced encryption algorithms, so-called asymmetric cryptography.
This process implies using a pair of large numbers called a public key and a private key to encrypt and decrypt data.
The public key converts a message into a code that can only be decrypted using a private key that’s known only to its owner.
