Difference Between Digital Signature and Digital Certificate

Digital utilities are being used in private offices, educational institutions, legal sector and various public sector work; Digitization has more precipitately increased to support web-based technologies, software-embedded systems, digital architecture, and various internet and computer-based contrivances. To maximize workflow and productivity, industries are more inclined to use digitally empowered solutions from signing their records to preserving their essential data.

Nowadays, it is of absolute importance to protect one's data from any cyber threat, spam, or forgery. The reason to implement signing utilities to sign electronic documents is that it guarantees the security and safety of your quintessential personal information, business records, documentation, etc.

Digital Signature has now become a modern-day signing tool to digitally sign documents and offers guaranteed cybersecurity solutions. Let us discuss a digital signature and digital certificate in detail.

Digital Signature: A Digital Signing Utility

A Digital Signature is a mathematical expression that is used in encrypting and decrypting your personal information. It is similar to your handwritten signature which authenticates your identity electronically. A digital signature is relatively safer and more secure in the signing of electronic documents, forms, or folders.

Digital Signatures works on encryption and decryption mechanisms. It is equipped with two cryptographic keys i.e a public key and a private key. In encryption, your message is encoded with a private key using certain algorithmic computations embedded with a hash value function. Similarly, in the decryption of your message, it is decoded with a public key assigned to intended receivers.
Therefore, Digital Signature is an algorithm-based mathematical technique to validate the integrity and authenticity of the information shared. It is commonly implemented by various industries, organizations, professionals, and business owners in their signing work as it functions on the basis of a cryptographic format.

Why Is Digital Signature Required For Signing Purposes?

Digital Signature maintains the integrity and authenticity of the data. As the message sent to a receiver is encrypted and can be decrypted by using a public key. That's why it electronically authenticates the sent data.
It offers a double-layer cyber security assistance to your information shared online. Hence, it abates the risks of cyber attacks.

It offers legal non-repudiation rights to the receivers. The sender of the message can not deny or reject the message sent to receivers. They have to comply with the originality of the message.
A digital signature helps in the remote signing of documents. As electronic signatures guarantee a more secure and safer approach to signing processes.

What Is A Digital Certificate?

A Digital Certificate is similar to a physical paper-based certificate that is used to store your personal information in an electronic format. So, it basically records all your credentials safely and securely. It electronically validates the identity of a certificate holder by using a cryptographic mechanism (encryption and decryption of a message). A digital signature is attached with your digital certificate to avail of the signing facility.

Who Can Issue A Digital Certificate?

Digital Certificates are issued by the Licensed Certifying/Certificate Authorities. Capricorn CA is a licensed Certificate Authority CA in India which is regulated by the Controller of Certifying Authority CCA. We offer DSC and various other signing solutions to our customers after the completion of their domain validation. It is a core responsibility of a certifying authority to verify each and every detail of an applicant and then create a digital signature certificate for them.

Difference Between A Digital Signature & A Digital Certificate

A salient difference between a digital signature and a digital certificate is that a digital certificate is used to store the digital signature assigned to an authorized entity. On the other hand, a digital signature helps in secure signing processes and uses an encryption method for sending the data.

A digital certificate collects all your credentials in an electronic format that is used to validate a sender's identity by using a Public Key Infrastructure PKI. A digital signature is an algorithmic computation that encrypts a message in hash values and a similar hash function will be used to verify/decrypt the sender's message by using a public key. So, the endmost difference is that a digital certificate confirms a signer's identity whereas a digital signature validates the information shared.


For safe signing processes, a digital signature plays a pivotal role in protecting vital personal data from any cyber fraud, theft, or forgery. The electronic documents that are digitally signed with a digital certificate contain the original information as it is after being shared with an intended participant. Thus, it develops a sense of trust between both parties. Now, you can ensure complete cybersecurity of your personal data by acknowledging a digital signature in your various signing processes.
