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. 56 * 57 */ 58 public abstract class SunJSSE extends java.security.Provider { 59 60 private static final long serialVersionUID = 3231825739635378733L; 61 62 private static String info = "Sun JSSE provider" + 63 "(PKCS12, SunX509/PKIX key/trust factories, " + 64 "SSLv3/TLSv1/TLSv1.1/TLSv1.2)"; 65 66 private static String fipsInfo = 67 "Sun JSSE provider (FIPS mode, crypto provider "; 68 69 // tri-valued flag: 70 // null := no final decision made 71 // false := data structures initialized in non-FIPS mode 72 // true := data structures initialized in FIPS mode 73 private static Boolean fips; 74 75 // the FIPS certificate crypto provider that we use to perform all crypto 76 // operations. null in non-FIPS mode 77 static java.security.Provider cryptoProvider; 78 79 protected static synchronized boolean isFIPS() { 80 if (fips == null) { 81 fips = false; 82 } 83 return fips; 84 } 85 86 // ensure we can use FIPS mode using the specified crypto provider. 87 // enable FIPS mode if not already enabled. 88 private static synchronized void ensureFIPS(java.security.Provider p) { 89 if (fips == null) { 90 fips = true; 91 cryptoProvider = p; 92 } else { 93 if (fips == false) { 94 throw new ProviderException 95 ("SunJSSE already initialized in non-FIPS mode"); 96 } 97 if (cryptoProvider != p) { 98 throw new ProviderException 99 ("SunJSSE already initialized with FIPS crypto provider " 100 + cryptoProvider); 101 } 102 } 103 } 104 105 // standard constructor 106 protected SunJSSE() { 107 super("SunJSSE", 1.9d, info); 108 subclassCheck(); 109 if (Boolean.TRUE.equals(fips)) { 110 throw new ProviderException 111 ("SunJSSE is already initialized in FIPS mode"); 112 } 113 registerAlgorithms(false); 114 } 115 116 // preferred constructor to enable FIPS mode at runtime 117 protected SunJSSE(java.security.Provider cryptoProvider){ 118 this(checkNull(cryptoProvider), cryptoProvider.getName()); 119 } 120 121 // constructor to enable FIPS mode from java.security file 122 protected SunJSSE(String cryptoProvider){ 123 this(null, checkNull(cryptoProvider)); 124 } 125 126 private static <T> T checkNull(T t) { 127 if (t == null) { 128 throw new ProviderException("cryptoProvider must not be null"); 129 } 130 return t; 131 } 132 133 private SunJSSE(java.security.Provider cryptoProvider, 134 String providerName) { 135 super("SunJSSE", 1.9d, fipsInfo + providerName + ")"); 136 subclassCheck(); 137 if (cryptoProvider == null) { 138 // Calling Security.getProvider() will cause other providers to be 139 // loaded.
