  • What is a Digital Certificate?
    • A digital certificate is a form of identification for use with web-based applications.
    • The digital certificate is associated with the individualís public key.
    • The corresponding private key contains unique code that is not shared with any subscriber or application. The private key verifies the public key in PKI transactions.
    • The certificate containing the public key is used by PKI applications to identify the user.
      • The Certification Authority is the controlling application that determines that the individual with a certificate is who they say they are within a specified level of assurance.
      • All certificates have the CAís signature on the certificate for authenticity.
    • The public/private key system allows data encrypted by one key to be decrypted by the other.
