+ * Generate a pair of keys, and provide access to them.  This class is
+ * provided primarily for ease of use.
+ *
+ * <P>This provides some simple certificate management functionality.
+ * Specifically, it allows you to create self-signed X.509 certificates
+ * as well as PKCS 10 based certificate signing requests.
+ *
+ * <P>Keys for some public key signature algorithms have algorithm
+ * parameters, such as DSS/DSA.  Some sites' Certificate Authorities
+ * adopt fixed algorithm parameters, which speeds up some operations
+ * including key generation and signing.  <em>At this time, this interface
+ * does not provide a way to provide such algorithm parameters, e.g.
+ * by providing the CA certificate which includes those parameters.</em>
+ *
+ * <P>Also, note that at this time only signature-capable keys may be
+ * acquired through this interface.  Diffie-Hellman keys, used for secure
+ * key exchange, may be supported later.
