| 32 | * The JSSE provider. | ||
| 33 | * | ||
| 34 | * The RSA implementation has been removed from JSSE, but we still need to | ||
| 35 | * register the same algorithms for compatibility. We just point to the RSA | ||
| 36 | * implementation in the SunRsaSign provider. This works because all classes | ||
| 37 | * are in the bootclasspath and therefore loaded by the same classloader. | ||
| 38 | * | ||
| 39 | * SunJSSE now supports an experimental FIPS compliant mode when used with an | ||
| 40 | * appropriate FIPS certified crypto provider. In FIPS mode, we: | ||
| 41 | * . allow only TLS 1.0 or later | ||
| 42 | * . allow only FIPS approved ciphersuites | ||
| 43 | * . perform all crypto in the FIPS crypto provider | ||
| 44 | * | ||
| 45 | * It is currently not possible to use both FIPS compliant SunJSSE and | ||
| 46 | * standard JSSE at the same time because of the various static data structures | ||
| 47 | * we use. | ||
| 48 | * | ||
| 49 | * However, we do want to allow FIPS mode to be enabled at runtime and without | ||
| 50 | * editing the java.security file. That means we need to allow | ||
| 51 | * Security.removeProvider("SunJSSE") to work, which creates an instance of | ||
| 52 | * this class in non-FIPS mode. That is why we delay the selection of the mode | ||
| 53 | * as long as possible. This is until we open an SSL/TLS connection and the | ||
| 54 | * data structures need to be initialized or until SunJSSE is initialized in | ||
| 55 | * FIPS mode. | ||
