/** |
|
55 |
* Many data structures are involved in the handshake messages. These |
|
56 |
* classes are used as structures, with public data members. They are |
|
57 |
* not visible outside the SSL package. |
|
58 |
* |
|
59 |
* Handshake messages all have a common header format, and they are all |
|
60 |
* encoded in a "handshake data" SSL record substream. The base class |
|
61 |
* here (HandshakeMessage) provides a common framework and records the |
|
62 |
* SSL record type of the particular handshake message. |
|
63 |
* |
|
64 |
* This file contains subclasses for all the basic handshake messages. |
|
65 |
* All handshake messages know how to encode and decode themselves on |
|
66 |
* SSL streams; this facilitates using the same code on SSL client and |
|
67 |
* server sides, although they don't send and receive the same messages. |
|
68 |
* |
|
69 |
* Messages also know how to print themselves, which is quite handy |
|
70 |
* for debugging. They always identify their type, and can optionally |
|
71 |
* dump all of their content. |

* ServerKeyExchange ... SERVER --> CLIENT |
898 |
* |
|
899 |
* The cipher suite selected, when combined with the certificate exchanged, |
|
900 |
* implies one of several different kinds of key exchange. Most current |
|
901 |
* cipher suites require the server to send more than its certificate. |
|
902 |
* |
|
903 |
* The primary exceptions are when a server sends an encryption-capable |
|
904 |
* RSA public key in its cert, to be used with RSA (or RSA_export) key |
|
905 |
* exchange; and when a server sends its Diffie-Hellman cert. Those kinds |
|
906 |
* of key exchange do not require a ServerKeyExchange message. |
|
907 |
* |
|
908 |
* Key exchange can be viewed as having three modes, which are explicit |
|
909 |
* for the Diffie-Hellman flavors and poorly specified for RSA ones: |
|
910 |
* |
|
911 |
* - "Ephemeral" keys. Here, a "temporary" key is allocated by the |
|
912 |
* server, and signed. Diffie-Hellman keys signed using RSA or |
|
913 |
* DSS are ephemeral (DHE flavor). RSA keys get used to do the same |
|
914 |
* thing, to cut the key size down to 512 bits (export restrictions) |
|
915 |
* or for signing-only RSA certificates. |
|
916 |
* |
|
917 |
* - Anonymity. Here no server certificate is sent, only the public |
|
918 |
* key of the server. This case is subject to man-in-the-middle |
|
919 |
* attacks. This can be done with Diffie-Hellman keys (DH_anon) or |
|
920 |
* with RSA keys, but is only used in SSLv3 for DH_anon. |
|
921 |
* |
|
922 |
* - "Normal" case. Here a server certificate is sent, and the public |
|
923 |
* key there is used directly in exchanging the premaster secret. |
|
924 |
* For example, Diffie-Hellman "DH" flavor, and any RSA flavor with |
|
925 |
* only 512 bit keys. |
|
926 |
* |
|
927 |
* If a server certificate is sent, there is no anonymity. However, |
|
928 |
* when a certificate is sent, ephemeral keys may still be used to |
|
929 |
* exchange the premaster secret. That's how RSA_EXPORT often works, |
|
930 |
* as well as how the DHE_* flavors work. |
