When a document is digitally signed, a mathematical algorithm is used to generate a unique digital fingerprint of the document. This fingerprint, also known as a hash, is encrypted using the signer’s private key. The encrypted hash, along with the signer’s public key, is attached to the document, creating a digital signature.

To validate the digital signature, the recipient of the signed document can decrypt the encrypted hash using the signer’s public key. The recipient then computes a hash of the document and compares it to the decrypted hash. If the two hashes match, it confirms that the document has not been altered since it was signed and that the signer’s identity is verified.

Electronic certificates come into play in the process of verifying digital signatures. The digital signature is attached to the document along with the signer’s electronic certificate, which contains their public key. The recipient uses the public key from the electronic certificate to verify the digital signature.

Before trusting the digital signature, the recipient verifies the authenticity of the electronic certificate by checking its digital signature against the public key of the trusted Certificate Authority (CA) who issued the certificate. If the digital signature of the electronic certificate is valid, the recipient can trust the public key contained within the certificate.

By combining digital signatures and electronic certificates, the integrity and authenticity of digital documents can be assured. This ensures non-repudiation – the signer cannot deny their signature – and provides a secure and reliable method of verifying the identity of the signer.
