The comparison of algorithm names was inconsistent, sometimes `equals` and sometimes `equalsIgnoreCase`. This is even more suspicious in the `P11KeyAgreement` where both were used. My understanding is that `equalsIgnoreCase` should always be used because key algorithm has always been case-insensitive. Also, since the "TlsPremasterSecret" algorithm is only used internally, it is always provided with the correct case.
