This information is likely to change 402 * over time, since the export control rules are no static technical issue. 403 * 404 * Independent of the export flag the cipher strength is sorted into classes. 405 * SSL_EXP40 was denoting the 40bit US export limit of past times, which now 406 * is at 56bit (SSL_EXP56). If the exportable cipher class is going to change 407 * again (eg. to 64bit) the use of "SSL_EXP*" becomes blurred even more, 408 * since SSL_EXP64 could be similar to SSL_LOW. 409 * For this reason SSL_MICRO and SSL_MINI macros are included to widen the 410 * namespace of SSL_LOW-SSL_HIGH to lower values. As development of speed 411 * and ciphers goes, another extension to SSL_SUPER and/or SSL_ULTRA would 412 * be possible. 413 */ 414 #define SSL_EXP_MASK 0x00000003L 415 #define SSL_STRONG_MASK 0x000001fcL 416 417 #define SSL_NOT_EXP 0x00000001L 418 #define SSL_EXPORT 0x00000002L 419 420 #define SSL_STRONG_NONE 0x00000004L 421 #define SSL_EXP40 0x00000008L 422 #define SSL_MICRO (SSL_EXP40) 423 #define SSL_EXP56 0x00000010L 424 #define SSL_MINI (SSL_EXP56) 425 #define SSL_LOW 0x00000020L 426 #define SSL_MEDIUM 0x00000040L 427 #define SSL_HIGH 0x00000080L 428 #define SSL_FIPS 0x00000100L 429 430 /* we have used 000001ff - 23 bits left to go */ 431 432 /* 433 * Macros to check the export status and cipher strength for export ciphers. 434 * Even though the macros for EXPORT and EXPORT40/56 have similar names, 435 * their meaning is different: 436 * *_EXPORT macros check the 'exportable' status. 437 * *_EXPORT40/56 macros are used to check whether a certain cipher strength 438 * is given. 439 * Since the SSL_IS_EXPORT* and SSL_EXPORT* macros depend on the correct 440 * algorithm structure element to be passed (algorithms, algo_strength) and no 441 * typechecking can be done as they are all of type unsigned long, their 442 * direct usage is discouraged. 443 * Use the SSL_C_* macros instead. 444 */ 445 #define SSL_IS_EXPORT(a) ((a)&SSL_EXPORT) 446 #define SSL_IS_EXPORT56(a) ((a)&SSL_EXP56) 447 #define SSL_IS_EXPORT40(a) ((a)&SSL_EXP40) 448 #define SSL_C_IS_EXPORT(c) SSL_IS_EXPORT((c)->algo_strength) 449 #define SSL_C_IS_EXPORT56(c) SSL_IS_EXPORT56((c)->algo_strength) 450 #define SSL_C_IS_EXPORT40(c) SSL_IS_EXPORT40((c)->algo_strength) 451 452 #define SSL_EXPORT_KEYLENGTH(a,s) (SSL_IS_EXPORT40(s) ? 5 : \ 453 (a) == SSL_DES ? 8 : 7) 454 #define SSL_EXPORT_PKEYLENGTH(a) (SSL_IS_EXPORT40(a) ? 512 : 1024) 455 #define SSL_C_EXPORT_KEYLENGTH(c) SSL_EXPORT_KEYLENGTH((c)->algorithm_enc, \ 456 (c)->algo_strength) 457 #define SSL_C_EXPORT_PKEYLENGTH(c) SSL_EXPORT_PKEYLENGTH((c)->algo_strength) 458 459 460 461 462 /* Mostly for SSLv3 */ 463 #define SSL_PKEY_RSA_ENC 0 464 #define SSL_PKEY_RSA_SIGN 1 465 #define SSL_PKEY_DSA_SIGN 2 466 #define SSL_PKEY_DH_RSA 3 467 #define SSL_PKEY_DH_DSA 4 468 #define SSL_PKEY_ECC 5 469 #define SSL_PKEY_GOST94 6 470 #define SSL_PKEY_GOST01 7 471 #define SSL_PKEY_NUM 8 472 473 /* SSL_kRSA <- RSA_ENC | (RSA_TMP & RSA_SIGN) | 474 * <- (EXPORT & (RSA_ENC | RSA_TMP) & RSA_SIGN) 475 * SSL_kDH <- DH_ENC & (RSA_ENC | RSA_SIGN | DSA_SIGN) 476 * SSL_kEDH <- RSA_ENC | RSA_SIGN | DSA_SIGN 477 * SSL_aRSA <- RSA_ENC | RSA_SIGN 478 * SSL_aDSS <- DSA_SIGN 479 */ 480 481 /* 482 #define CERT_INVALID 0 483 #define CERT_PUBLIC_KEY 1 484 #define CERT_PRIVATE_KEY 2 485 */ 486 487 #ifndef OPENSSL_NO_EC 488 /* From ECC-TLS draft, used in encoding the curve type in 489 * ECParameters 490 */ 491 #define EXPLICIT_PRIME_CURVE_TYPE 1 492 #define EXPLICIT_CHAR2_CURVE_TYPE 2 493 #define NAMED_CURVE_TYPE 3 494 #endif /* OPENSSL_NO_EC */ 495 496 typedef struct cert_pkey_st 497 { 498 X509 *x509;
