Click here to renew the cryptographic key
Renews your cryptographic keys.
It is good to renew the cryptographic keys on your computer periodically, such as once a year. Also, renew your cryptographic keys any time you suspect they have been compromised. This will reduce the chance that your private key has been tampered with.
When you renew the cryptographic keys for your computer, any messages that were encrypted with the previous public keys cannot be read. This occurs only until the new public keys are replicated in Active Directory Domain Services (AD DS) to all Message Queuing servers, and until the computer starts using the new public keys.
