Answer:
If the private key associated with a digital certificate becomes compromised, the certificate should be revoked and a new certificate should be issued with a new private key.
A digital certificate is used to authenticate the identity of a user or organization in electronic transactions, and it is issued by a certificate authority (CA). The certificate includes a public key and a private key, which are used to encrypt and decrypt data.
If the private key associated with the digital certificate becomes compromised, it means that an unauthorized party may have gained access to the key and could potentially use it to impersonate the holder of the certificate. This could compromise the security of electronic transactions and put sensitive information at risk.
To prevent this, the certificate should be immediately revoked by the issuing CA, and a new certificate should be issued with a new private key. This will ensure that any future transactions using the certificate will be secure and that the identity of the holder can be properly authenticated.
