Digital Signature for Zoho Sign
A modern alternative to paper and pen
Digital Sign for Zoho Sign uses an advanced mathematical technique to check the authenticity and integrity of digital messages and documents. Guarantee the contents of your message are not altered in transit and overcome the problem of impersonation and tampering in digital communications.
The role of digital signatures
Digital signatures provide additional information such as the origin of the message, status, and consent by the signer.
- In many regions, including parts of North America, the European Union, and APAC, digital signatures are considered legally binding and hold the same value as traditional document signatures.
- In addition to digital document signing, they are also used for financial transactions, email service providers, and software distribution, areas where the authenticity and integrity of digital communications are crucial.
- Industry-standard technology called public key infrastructure ensures a digital signature's data authenticity and integrity.
How do digital signatures work?
Using a mathematical algorithm, digital signing solution providers such as Zoho Sign will generate two keys: a public key and a private key. When a signer digitally signs a document, a cryptographic hash is generated for the document.
That cryptographic hash is then encrypted using the sender's private key, which is stored in a secure HSM box. It is then appended to the document and sent to the recipients along with the sender's public key.
The recipient can decrypt the encrypted hash with the sender's public key certificate. A cryptographic hash is again generated on the recipient's end.
Both cryptographic hashes are compared to check its authenticity. If they match, the document hasn't been tampered with and is considered valid.
