A digital certificate typically contains the subject's public key, the identity of the certificate holder (such as their name and email address), the certificate authority (CA) that issued it, a digital signature from the CA, and the certificate's validity period. It may also include additional metadata, such as the certificate's serial number and the algorithms used for encryption and signing. This information helps verify the authenticity of the key and the identity of the certificate holder.
A Digital Signature Certificate, is a digital identity of the sender filing the documents through internet .Digital Signature Certificate is a digital equivalent of a hand written signature which has an extra data attached electronically to any message or a document.
A digital certificate serial number is a unique identifier assigned to a digital certificate by the issuing Certificate Authority (CA). This number helps identify and distinguish the certificate from others in the CA's database, ensuring its authenticity and integrity. It plays a crucial role in managing certificates, particularly in processes like revocation and validation. Each serial number is typically unique to prevent duplication and ensure secure communications.

A digital certificate is an electronic document used to prove the ownership of a public key, often as part of a public key infrastructure (PKI). It typically contains information about the key, the identity of its owner, and the digital signature of the certificate authority (CA) that issued it. Digital certificates are essential for secure online communications, enabling encryption and authentication in various applications like SSL/TLS for websites. They help ensure that data exchanges are secure and that the parties involved are who they claim to be.
A digital certificate confirms the information has come from the source it's claimed to be, and that the site is encrypted for transactions to be exchanged.
An "invalid certificate" on your DSI (Digital Secure Identifier) typically indicates that the digital certificate used to authenticate a connection is either expired, not trusted, or has been revoked. This can prevent secure communication and may expose your data to security risks. To resolve this issue, you may need to update the certificate, check your device's date and time settings, or install a trusted certificate authority's root certificate. It's important to address this promptly to maintain the integrity and security of your connections.
A DPR certificate, or Digital Payment Receipt certificate, is a document that serves as proof of transaction for digital payments made through various platforms. It typically includes details such as the transaction amount, date, time, and the parties involved. This certificate can be used for record-keeping, financial audits, or verifying payments in business transactions. It is particularly relevant in contexts where electronic payments are prevalent, ensuring transparency and accountability.
The file extension for an exported certificate backup file is typically .pfx or .p12. These formats are used to bundle a private key with the corresponding certificate, and they can include an entire certificate chain. Another common format is .cer, which may contain just the public certificate.
A digital certificate may be revoked for several reasons, including the compromise of the private key associated with the certificate, expiration of the certificate, or if the certificate was issued based on fraudulent information. Additionally, if the certificate holder no longer requires the certificate or has changed their affiliation, revocation may be necessary. Revocation ensures that entities relying on the certificate can trust that it is no longer valid.
