It is very important to keep your eCommerce transactions safe, and digital signatures are a big part of ensuring everything stays safe and real. For businesses to remain safe, they need to know how these signatures and certificates work as the number of online interactions grows.
This blog post will explain digital signatures, how they work, and why they’re important for your eCommerce site. Learn how these tools can help you trust others and keep your online transactions safe.
Today we will look more closely at how these signatures protect your online transactions.
Key Takeaways:
Digital Signatures Use Cryptography for Security: Unlike simple electronic signatures, digital signatures use cryptographic techniques, specifically public and private keys, to ensure the authenticity, integrity, and security of digital documents.
Public Key Infrastructure (PKI) Supports Digital Signatures: PKI provides the framework for managing digital certificates and cryptographic keys, ensuring that the public key used to verify a signature matches the identity validated by a certificate authority (CA).
Digital Certificates Ensure Trust and Identity: A digital certificate issued by a trusted CA binds the signer’s identity to a public key, allowing recipients to verify the authenticity of the signer and ensuring the integrity of the signed document.
Legal Recognition of Digital Signatures: In many countries, including the US (via the E-SIGN Act) and the EU (via the eIDAS Regulation), these are legally recognized, providing the same legal standing as handwritten signatures for eCommerce transactions.
Best Practices for Digital Signatures: To maintain security, it’s crucial to secure private keys, use trusted software, regularly renew certificates, and educate employees about the proper use of these signatures to prevent unauthorized use.
What is a Digital Signature, and How Does it Work?

A digital signature is a type of electronic signature that uses cryptographic techniques to offer higher levels of security and authenticity. Unlike a simple electronic signature, which might merely be an image of a handwritten signature or a typed name, it utilize a mathematical algorithm to create a unique digital document that only the signer can produce.
This process involves the use of a private key to encrypt the signature and a corresponding public key to decrypt and validate it, ensuring the document’s integrity.
How is a Digital Signature Different from an Electronic Signature?
While both digital signatures and electronic signatures serve to authenticate the identity of the signer, they operate on fundamentally different principles. An electronic signature can be as simple as a name typed at the end of an email or an image of a handwritten signature.
In contrast, a digital signature is a more advanced type of electronic signature that leverages cryptographic principles to provide a higher level of security and non-repudiation. It employs public key infrastructure (PKI) to ensure that the signature is both unique and verifiable.
