Finding certificates by thumbprint is a pretty common scenario, so we can eliminate a 20-byte allocation per-certificate-searched when searching by thumbprint.
GetCertHashreturns a defensive copy of the thumbprint. Instead, we can get the thumbprint in a stack buffer, and do an upfront check on the size of the to-be-found thumbprint.
