+/**
+ * A password encoder that delegates to another PasswordEncoder based upon a prefixed
+ * identifier.
+ *
+ * <h2>Constructing an instance</h2>
+ *
+ *
+ * <pre>
+ * String idForEncode = "bcrypt";
+ * Map<String,PasswordEncoder> encoders = new HashMap<>();
+ * encoders.put(idForEncode, new BCryptPasswordEncoder());
+ * encoders.put("noop", NoOpPasswordEncoder.getInstance());
+ * encoders.put("pbkdf2", new Pbkdf2PasswordEncoder());
+ * encoders.put("scrypt", new SCryptPasswordEncoder());
+ * encoders.put("sha256", new StandardPasswordEncoder());
+ *
+ * PasswordEncoder passwordEncoder = new DelegatingPasswordEncoder(idForEncode, encoders);
+ * </pre>
+ *
+ *
+ * <h2>Password Storage Format</h2>
+ *
+ * The general format for a password is:
+ *
+ * <pre>
+ * {id}encodedPassword
+ * </pre>
+ *
+ * Such that "id" is an identifier used to look up which {@link PasswordEncoder} should
+ * be used and "encodedPassword" is the original encoded password for the selected
+ * {@link PasswordEncoder}. The "id" must be at the beginning of the password, start with
+ * "{" and end with "}". If the "id" cannot be found, the "id" will be null.
+ *
+ * For example, the following might be a list of passwords encoded using different "id".
+ * All of the original passwords are "password".
+ *
+ * <pre>
+ * {bcrypt}$2a$10$dXJ3SW6G7P50lGmMkkmwe.20cQQubK3.HZWzG3YB1tlRy.fqvM/BG
+ * {noop}password
+ * {pbkdf2}5d923b44a6d129f3ddf3e3c8d29412723dcbde72445e8ef6bf3b508fbf17fa4ed4d6b99ca763d8dc
+ * {scrypt}$e0801$8bWJaSu2IKSn9Z9kM+TPXfOc/9bdYSrN1oD9qfVThWEwdRTnO7re7Ei+fUZRJ68k9lTyuTeUp4of4g24hHnazw==$OAOec05+bXxvuu/1qZ6NUR+xQYvYv7BeL1QxwRpY5Pc=
+ * {sha256}97cde38028ad898ebc02e690819fa220e88c62e0699403e94fff291cfffaf8410849f27605abcbc0
+ * </pre>
+ *
+ * For the DelegatingPasswordEncoder that we constructed above:
+ *
+ * <ol>
+ * <li>The first password would have a {@code PasswordEncoder} id of "bcrypt" and
+ * encodedPassword of "$2a$10$dXJ3SW6G7P50lGmMkkmwe.20cQQubK3.HZWzG3YB1tlRy.fqvM/BG".
+ * When matching it would delegate to
+ * {@link org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder}</li>
+ * <li>The second password would have a {@code PasswordEncoder} id of "noop" and
+ * encodedPassword of "thisisextremelyunsafe". When matching it would delegate to
+ * {@link NoOpPasswordEncoder}</li>
+ * <li>The third password would have a {@code PasswordEncoder} id of "pbkdf2" and
+ * encodedPassword of
+ * "5d923b44a6d129f3ddf3e3c8d29412723dcbde72445e8ef6bf3b508fbf17fa4ed4d6b99ca763d8dc".
+ * When matching it would delegate to {@link Pbkdf2PasswordEncoder}</li>
+ * <li>The fourth password would have a {@code PasswordEncoder} id of "scrypt" and
+ * encodedPassword of
+ * "$e0801$8bWJaSu2IKSn9Z9kM+TPXfOc/9bdYSrN1oD9qfVThWEwdRTnO7re7Ei+fUZRJ68k9lTyuTeUp4of4g24hHnazw==$OAOec05+bXxvuu/1qZ6NUR+xQYvYv7BeL1QxwRpY5Pc="
+ * When matching it would delegate to
+ * {@link org.springframework.security.crypto.scrypt.SCryptPasswordEncoder}</li>
+ * <li>The final password would have a {@code PasswordEncoder} id of "sha256" and
+ * encodedPassword of
+ * "97cde38028ad898ebc02e690819fa220e88c62e0699403e94fff291cfffaf8410849f27605abcbc0".
+ * When matching it would delegate to {@link StandardPasswordEncoder}</li>
+ * </ol>
+ *
+ * <h2>Password Encoding</h2>
+ *
+ * The @{code idForEncode} passed into the constructor determines which
+ * {@link PasswordEncoder} will be used for encoding passwords. In the
+ * {@code DelegatingPasswordEncoder} we constructed above, that means that the result of
+ * encoding "password" would be delegated to {@code BCryptPasswordEncoder} and be prefixed
+ * with "{bcrypt}". The end result would look like:
+ *
+ * <pre>
+ * {bcrypt}$2a$10$dXJ3SW6G7P50lGmMkkmwe.20cQQubK3.HZWzG3YB1tlRy.fqvM/BG
+ * </pre>
+ *
+ * <h2>Password Matching</h2>
+ *
+ * Matching is done based upon the "id" and the mapping of the "id" to the
+ * {@link PasswordEncoder} provided in the constructor. Our example in "Password Storage
+ * Format" provides a working example of how this is done.
+ *
+ * By default the result of invoking {@link #matches(CharSequence, String)} with a
+ * password with an "id" that is not mapped (including a null id) will result in an
+ * {@link IllegalArgumentException}. This behavior can be customized using
+ * {@link #setDefaultPasswordEncoderForMatches(PasswordEncoder)}.
