SSL/Cert/SHA1 Registry Key
The SHA1 cryptographic hash function is no longer considered to be secure.
It remains secure for most of the world but those with sufficient resources
are assumed now to be capable of breaking it. The JNIOR now uses the SHA256
algorithm (SHA2). You can disable use of SHA2 if you need to communicate
securely with legacy systems. This is achieved by setting this key to TRUE.
As with most of the settings in this category, changes take effect when the
certificate is regenerated.
