Certificate authority server definition
Certificate authority server is an easy-to-use and secure solution for creating and storing asymmetric key pairs, which are used for public-key infrastructure (PKI), decryption, signing, and validation. To digitally sign firmware updates, code, and other items requiring a digital signature, the certificate authority server creates a root certificate. Certificate enrollment requests are handled by certificate authority servers, which can issue and revoke digital certificates. All CA servers are identity management ready. The usage of PKI allows businesses to effectively protect their customers' identities. This allows users to securely sign and encrypt their electronic mail, log in to their networks, and access the internet via their mobile devices.
Functions of a CA server:
- Examines public documents to confirm the legitimacy of businesses, people, and domain names
- Provides server, user, and admin authentication via digital certificates
- Keeps track of certificate revocations to show when certificates are rendered useless ahead of their expiration dates
- Allows both root and subordinate issuer CAs to be made
- Supports different logical PKIs made up of CAs that have their own certificate signing keys
- Allows you to set up different certificate profiles
- Uses reliable authentication methods for both users and administrators
Benefits of a CA server:
- Authentication by proving the entity's identification
- Encryption for safe Internet communication
- Certificate-signed documents cannot be altered in transit by a third party
