 /**
  * The JSSE provider.
  *
  * The RSA implementation has been removed from JSSE, but we still need to
  * register the same algorithms for compatibility. 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.
