As companies adopt an online approach to their business, they need to find a reliable way to validate the authenticity and integrity of electronic goods. They need to make sure that the items are not changed since they are created.
When it comes to digital transactions, they need to build a system that follows the legality of transactions. So they use a digital signature for this purpose. Digital signatures are the e-signatures re-defined version.

However, communicating through the internet requires trust in electronic identification (EID) of the parties to a transaction.
The use of a PKI-based digital certificate is a long-accepted technique for managing electronic identities. All these digital certificates need to be validated by the relying party because they may have been compromised or revoked after issuance. Deciding to trust digital certificates can be a complicated task.
How to validate digital signatures?
It is not difficult to verify or validate the digital signature. If you have a digital signature data that is generated, you can verify the authenticity of the signature. To do this, you need the data, signature and public key corresponding to the private key used for signing data.
This will allow the recipient to authenticate the identity of the signer and see the reason, the date, and time signatures. This ensures that the document was not tampered with or altered after the signature.
