Digital Signing

What is Digital Signing

Digital signing, or digital signature, is a technological method used to authenticate the integrity and authenticity of a digital document or message. It involves using cryptographic techniques that securely attach the signer’s identity to the document, ensuring that it hasn’t been tampered with.


Types of Digital Signatures

Digital signatures come in various types, each with different security levels and use cases.

Class 1 Digital Signature 

Primarily used for securing email communication, Class 1 signatures verify the name and email address of the sender.


Class 2 Digital Signature 

These are used for filing documents with government entities, verifying the identity of the signer beyond just their email.


Class 3 Digital Signature 

Offering the highest level of security, Class 3 signatures are used for online transactions and tendering processes, requiring the signer to present themselves before a certifying authority.


What is a Public Key Infrastructure (PKI)?

PKI is a framework that manages encryption keys and digital certificates, ensuring secure electronic transfer of information for various network activities like email, e-commerce, and digital signatures.


What is Certificate Authority? 

A Certificate Authority (CA) is an entity that issues digital certificates. These certificates validate the ownership of a public key by the named subject of the certificate, ensuring trustworthy communication and transactions online.


What is a Digital Certificate

A digital certificate, part of the PKI, is an electronic document that uses a digital signature to bind a public key with an identity. This process provides a level of trust, confirming that the public key belongs to the specified person or entity.


What is Digital Signing Software? 

Digital signing software allows users to apply digital signatures to documents. This software streamlines the process of signing documents electronically, ensuring security and compliance with legal standards.


Digital Signature Security 

Digital signatures are secured through cryptography, ensuring that documents are not altered in transit. They provide a secure way to verify the authenticity of digital messages or documents.


Digital Signature Use Cases 

Use cases include legal document signing, government filings, financial transactions, and any scenario requiring secure, verifiable signatures.
