Where can I get an intermediate in California?
In Windows environment, you may locate the intermediate certificates in the Intermediate Certification Authorities tab in local computer account console. All major Certificate Authorities use intermediate certificates because of the additional security level.
What is intermediate certificate?
The intermediate certificate is a certificate that was issued as a dividing layer between the Certificate Authority and the end user’s certificate. It serves as a verification device that tells a browser that a certificate was issued on a safe, valid source, the CA’s root certificate.
What’s the purpose of using an intermediate certificate?
The purpose of using an intermediate CA is primarily for security. The root key can be kept offline and used as infrequently as possible. If the intermediate key is compromised, the root CA can revoke the intermediate certificate and create a new intermediate cryptographic pair.
What’s the difference between root and intermediate CA?
The Root CA is the top level of certificate chain while intermediate CAs or Sub CAs are Certificate Authorities that issue off an intermediate root. Typically, the root CA does not sign server or client certificates directly.
Can a root CA sign a server certificate?
Typically, the root CA does not sign server or client certificates directly. The root CA is only ever used to create one or more intermediate CAs, which are trusted by the root CA to sign certificates on their behalf. This is best practice.
Do you need a CA to use client certificates?
So yes, you do need your own CA in order to use client certificates the way you’re wanting to use them. That said, every service that needs to verify one of those certificates would need a copy of the CA’s public key in their trust store.
