A Digital Signature Certificate (DSC) is an advance secure digital key that certifies the identity of the holder of DSC, issued by a Certifying Authority (CA). A Digital Signature Certificate contains subscriber's identity or KYC like name, email, country, APNIC account name and his public key.
Digital Certificates use PKI Public Key Infrastructure meaning data that has been digitally signed or encrypted by a private key can only be decrypted by its corresponding public key.
Message encryption provides confidentiality. Allows users to encrypt the document with the general public key which may be decrypted only with the corresponding private key. To put it in simple terms when encrypting, you employ their public key to write down message and recipient uses their private key to read it. One of the foremost secure way of protecting confidential documents.
Message or document signing binds the identity of the message source to the message. The signing of documents or messages ensures data integrity, message authentication, and non-repudiation altogether at the same time. When signing, you use your private key to write the message’s signature, and they use your public key to check if it’s really yours.
Class 1 digital signature certificates are usually issued to individuals or private entities or want to use it for personal use.
