Any IssuingAuthority in [IssuingAuthorities] that contains both the thumbprint in [Thumbprints] and issuer in [Issuers] will be considered a valid pair.

If you choose to override this method please be aware of the need to use the appropriate case when comparing keys. X509Thumbprints are case insensitive. Comparing keys using as case sensitive could lead to security issues.
