+ * Provider class for the Elliptic Curve provider.
+ * Supports EC keypair and parameter generation, ECDSA signing and
+ * ECDH key agreement.
+ *
+ * IMPLEMENTATION NOTE:
+ * The Java classes in this provider access a native ECC implementation
+ * via JNI to a C++ wrapper class which in turn calls C functions.
+ * The Java classes are packaged into the signed sunec.jar in the JRE
+ * extensions directory and the C++ and C functions are packaged into
+ * libsunecc.so or sunecc.dll in the JRE native libraries directory.
+ *
+ * @since   1.7
