514 | * cipher suites req uire the s erver to s end more t han its ce rtificate. | |
515 | * | |

521 | * Key exc hange can be viewed as having three mode s, which a re explici t | |
522 | * for the Diffie-He llman flav ors and po orly speci fied for R SA ones: | |
523 | * | |
524 | * - "Ephemeral " keys. H ere, a "te mporary" k ey is allo cated by t he | |
525 | * server, an d signed. Diffie-He llman keys signed us ing RSA or | |
526 | * DSS are ep hemeral (D HE flavor) . RSA key s get used to do the same | |

528 | * or for sig ning-only RSA certif icates. | |
529 | * | |
530 | * - Anonymity. Here no server cer tificate i s sent, on ly the pub lic | |
531 | * key of the server. This case is subject to man-in -the-middl e | |
532 | * attacks. This can b e done wit h Diffie-H ellman key s (DH_anon ) or | |
533 | * with RSA k eys, but i s only use d in SSLv3 for DH_an on. | |
534 | * | |

536 | * key there is used di rectly in exchanging the prema ster PW . | |
537 | * For exampl e, Diffie- Hellman "D H" flavor, and any R SA flavor with | |
538 | * only 512 b it keys. | |
539 | * | |
540 | * If a se rver certi ficate is sent, ther e is no an onymity. However, | |
541 | * when a certificat e is sent, ephemeral keys may still be u sed to | |
