    33  * The JSSE provider.

    34  *

    35  * The RSA implementation has been removed from JSSE, but we still need to

    36  * register the same algorithms for compatibility. We just point to the RSA

    37  * implementation in the SunRsaSign provider. This works because all classes

    38  * are in the bootclasspath and therefore loaded by the same classloader.

    39  *

    40  * SunJSSE now supports an experimental FIPS compliant mode when used with an

    41  * appropriate FIPS certified crypto provider. In FIPS mode, we:

    42  *  . allow only TLS 1.0 or later

    43  *  . allow only FIPS approved ciphersuites

    44  *  . perform all crypto in the FIPS crypto provider

    45  *

    46  * It is currently not possible to use both FIPS compliant SunJSSE and

    47  * standard JSSE at the same time because of the various static data structures

    48  * we use.

    49  *

    50  * However, we do want to allow FIPS mode to be enabled at runtime and without

    51  * editing the java.security file. That means we need to allow

    52  * Security.removeProvider("SunJSSE") to work, which creates an instance of

    53  * this class in non-FIPS mode. That is why we delay the selection of the mode

    54  * as long as possible. This is until we open an SSL/TLS connection and the

    55  * data structures need to be initialized or until SunJSSE is initialized in

    56  * FIPS mode.
