๐ What actually happens when you digitally sign a document?
A digital signature is much more than clicking โSign.โ
Behind every trusted digital signature is a process involving cryptographic hashing, private keys, digital certificates, public keys, and verification.
In this video, we break down the 6 key steps of the PKI Digital Signing Process:
1๏ธโฃ Document โ Start with the original document.
2๏ธโฃ Hash Generation โ Create a unique digital fingerprint using SHA-256.
3๏ธโฃ Digital Signature Creation โ Protect the hash using the signerโs private key.
4๏ธโฃ Signed Document Package โ Combine the document, signature, and certificate.
5๏ธโฃ Signature Verification โ Use the signerโs public key to verify the signature.
6๏ธโฃ Hash Comparison โ Compare the hashes to confirm authenticity and integrity.
When the hashes match, we know something important:
โ
The document is authentic.
โ
The document has not been altered.
โ
The digital signature is valid.
Thatโs the foundation of digital trust.
