PKI Digital Signature

Secured Signing uses Public Key Infrastructure (PKI) to provide the highest level of security and authenticity for digital signatures. PKI is a trusted method that ensures only the correct signer can sign a document, and once signed, the document can’t be changed without breaking the signature.

At the heart of the PKI system are two cryptographic keys:

  • A public key, which is available to everyone and used to encrypt data

  • A private key, which is known only to the signer and must be kept secure

How PKI Ensures Secure, Tamper-Proof Digital Signatures and Trusted Authorship

The magic of PKI lies in the unique connection between these two keys. A message or document encrypted with the public key can only be decrypted by the matching private key and vice versa. This guarantees that only the intended recipient or signer can access the content or authorize the signature.

When you sign a document with your private key through Secured Signing, the system creates a tamper-proof digital fingerprint of that document. If anyone attempts to change the document after it’s signed, the signature will immediately become invalid. This not only protects the integrity of the document but also provides unquestionable proof of authorship and consent.

Using PKI-based digital signatures also ensures secure end-to-end communication, meaning only the sender and the intended recipient can access or act on the document. This level of security is essential for industries that handle sensitive data, such as legal, financial, government, and healthcare sectors.
