CertificationAuthorities

HKLM\SOFTWARE\Microsoft\MSMQ\Parameters\

Description

The CertificationAuthorities subkey contains X509-V3 certificates from external certification authorities (CAs). These subkeys are created by the Microsoft Crypto API 2.0. Message Queuing uses the certificates to generate digital signatures that uniquely identify the message sender. The certificate and the digital signature are sent with each authenticated message.

Change method

To enable or disable certificates, in Control Panel, double-click MS Message Queue, click the Security tab, and then click the Certification Authorities button.

Note

The entries in the subkeys under CertificationAuthorities store actual certification authority (CA) certificates, not just pointers to entries in another location.

Caution

Do not change the value of entries in this subkey by editing the registry. Changing these values can disable the security features of Message Queuing.
