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. 57 * 58 */ 59public abstract class SunJSSE extends java.security.Provider { 60 61 private static final long serialVersionUID = 3231825739635378733L; 62 63 private static String info = "Sun JSSE provider" + 64 "(PKCS12, SunX509/PKIX key/trust factories, " + 65 "SSLv3/TLSv1/TLSv1.1/TLSv1.2/DTLSv1.0/DTLSv1.2)"; 66 67 private static String fipsInfo = 68 "Sun JSSE provider (FIPS mode, crypto provider "; 69 70 // tri-valued flag: 71 // null := no final decision made 72 // false := data structures initialized in non-FIPS mode 73 // true := data structures initialized in FIPS mode 74 private static Boolean fips; 75 76 // the FIPS certificate crypto provider that we use to perform all crypto 77 // operations. null in non-FIPS mode 78 static java.security.Provider cryptoProvider; 79 80 protected static synchronized boolean isFIPS() { 81 if (fips == null) { 82 fips = false; 83 } 84 return fips; 85 } 86 87 // ensure we can use FIPS mode using the specified crypto provider. 88 // enable FIPS mode if not already enabled. 89 private static synchronized void ensureFIPS(java.security.Provider p) { 90 if (fips == null) { 91 fips = true; 92 cryptoProvider = p; 93 } else { 94 if (fips == false) { 95 throw new ProviderException 96 ("SunJSSE already initialized in non-FIPS mode"); 97 } 98 if (cryptoProvider != p) { 99 throw new ProviderException 100 ("SunJSSE already initialized with FIPS crypto provider " 101 + cryptoProvider); 102 } 103 } 104 } 105 106 // standard constructor 107 protected SunJSSE() { 108 super("SunJSSE", PROVIDER_VER, info); 109 subclassCheck(); 110 if (Boolean.TRUE.equals(fips)) { 111 throw new ProviderException 112 ("SunJSSE is already initialized in FIPS mode"); 113 } 114 registerAlgorithms(false); 115 } 116 117 // preferred constructor to enable FIPS mode at runtime 118 protected SunJSSE(java.security.Provider cryptoProvider){ 119 this(checkNull(cryptoProvider), cryptoProvider.getName()); 120 } 121 122 // constructor to enable FIPS mode from java.security file 123 protected SunJSSE(String cryptoProvider){ 124 this(null, checkNull(cryptoProvider)); 125 } 126 127 private static <T> T checkNull(T t) { 128 if (t == null) { 129 throw new ProviderException("cryptoProvider must not be null"); 130 } 131 return t; 132 } 133 134 private SunJSSE(java.security.Provider cryptoProvider, 135 String providerName) { 136 super("SunJSSE", PROVIDER_VER, fipsInfo + providerName + ")"); 137 subclassCheck(); 138 if (cryptoProvider == null) { 139 // Calling Security.getProvider() will cause other providers to be 140 // loaded.
