We just point to the RSA * implementation in the SunRsaSign provider. This works because all classes * are in the bootclasspath and therefore loaded by the same classloader. * * SunJSSE now supports an experimental FIPS compliant mode when used with an * appropriate FIPS certified crypto provider. In FIPS mode, we: *  . allow only TLS 1.0 or later *  . allow only FIPS approved ciphersuites *  . perform all crypto in the FIPS crypto provider * * It is currently not possible to use both FIPS compliant SunJSSE and * standard JSSE at the same time because of the various static data structures * we use. * * However, we do want to allow FIPS mode to be enabled at runtime and without * editing the java.security file. That means we need to allow * Security.removeProvider("SunJSSE") to work, which creates an instance of * this class in non-FIPS mode. That is why we delay the selection of the mode * as long as possible. This is until we open an SSL/TLS connection and the * data structures need to be initialized or until SunJSSE is initialized in * FIPS mode. * */public abstract class SunJSSE extends java.security.Provider {     private static final long serialVersionUID = 3231825739635378733L;     private static String info = "Sun JSSE provider" +        "(PKCS12, SunX509 key/trust factories, SSLv3, TLSv1)";     private static String fipsInfo =        "Sun JSSE provider (FIPS mode, crypto provider ";     // tri-valued flag:    // null  := no final decision made    // false := data structures initialized in non-FIPS mode    // true  := data structures initialized in FIPS mode    private static Boolean fips;     // the FIPS certificate crypto provider that we use to perform all crypto    // operations. null in non-FIPS mode    static java.security.Provider cryptoProvider;     protected static synchronized boolean isFIPS() {        if (fips == null) {            fips = false;        }        return fips;    }     // ensure we can use FIPS mode using the specified crypto provider.    // enable FIPS mode if not already enabled.    private static synchronized void ensureFIPS(java.security.Provider p) {        if (fips == null) {            fips = true;            cryptoProvider = p;        } else {            if (fips == false) {                throw new ProviderException                    ("SunJSSE already initialized in non-FIPS mode");            }            if (cryptoProvider != p) {                throw new ProviderException                    ("SunJSSE already initialized with FIPS crypto provider "                    + cryptoProvider);            }        }    }     // standard constructor    protected SunJSSE() {        super("SunJSSE", 1.7d, info);        subclassCheck();        if (Boolean.TRUE.equals(fips)) {            throw new ProviderException                ("SunJSSE is already initialized in FIPS mode");        }        registerAlgorithms(false);    }     // prefered constructor to enable FIPS mode at runtime    protected SunJSSE(java.security.Provider cryptoProvider){        this(checkNull(cryptoProvider), cryptoProvider.getName());    }     // constructor to enable FIPS mode from java.security file    protected SunJSSE(String cryptoProvider){        this(null, checkNull(cryptoProvider));    }     private static <T> T checkNull(T t) {        if (t == null) {            throw new ProviderException("cryptoProvider must not be null");        }        return t;    }     private SunJSSE(java.security.Provider cryptoProvider,            String providerName) {        super("SunJSSE", 1.6d, fipsInfo + providerName + ")");        subclassCheck();        if (cryptoProvider == null) {            // Calling Security.getProvider() will cause other providers to be            // loaded.
