030:         * The Key interface is the top-level interface for all keys. It
031:         * defines the functionality shared by all key objects. All keys
032:         * have three characteristics:
033:         *
034:         * <UL>
035:         *
036:         * <LI>An Algorithm
037:         *
038:         * <P>This is the key algorithm for that key. The key algorithm is usually
039:         * an encryption or asymmetric operation algorithm (such as DSA or
040:         * RSA), which will work with those algorithms and with related
041:         * algorithms (such as MD5 with RSA, SHA-1 with RSA, Raw DSA, etc.)
042:         *
043:         * <LI>An Encoded Form
044:         *
045:         * <P>This is an external encoded form for the key used when a standard
046:         * representation of the key is needed outside the Java Virtual Machine,
047:         * as when transmitting the key to some other party. The key
048:         * is encoded according to a standard format (such as 
049:         * X.509 <code>SubjectPublicKeyInfo</code>).
050:         * Note: The syntax of the ASN.1 type <code>SubjectPublicKeyInfo</code> 
051:         * is defined as follows:
052:         *
053:         * <pre>
054:         * SubjectPublicKeyInfo ::= SEQUENCE {
055:         *   algorithm AlgorithmIdentifier,
056:         *   subjectPublicKey BIT STRING }
057:         *
058:         * AlgorithmIdentifier ::= SEQUENCE {
059:         *   algorithm OBJECT IDENTIFIER,
060:         *   parameters ANY DEFINED BY algorithm OPTIONAL }
061:         * </pre>
062:         * 
063:         * For more information, see 
064:         * <a href="http://www.ietf.org/rfc/rfc2459.txt">RFC 2459: 
065:         * Internet X.509 Public Key Infrastructure Certificate and CRL Profile</a>.
066:         * <P>
067:         *
068:         * <LI>A Format
069:         *

071:         *
072:         * </UL>
073:         *
074:         * Keys are generally obtained through key generators and certificates.
075:         * Keys may also be obtained from key specifications (transparent
076:         * representations of the underlying key material) through the use of a key
077:         * factory.
