This information is likely to change 413 * over time, since the export control rules are no static technical issue. 414 * 415 * Independent of the export flag the cipher strength is sorted into classes. 416 * SSL_EXP40 was denoting the 40bit US export limit of past times, which now 417 * is at 56bit (SSL_EXP56). If the exportable cipher class is going to change 418 * again (eg. to 64bit) the use of "SSL_EXP*" becomes blurred even more, 419 * since SSL_EXP64 could be similar to SSL_LOW. 420 * For this reason SSL_MICRO and SSL_MINI macros are included to widen the 421 * namespace of SSL_LOW-SSL_HIGH to lower values. As development of speed 422 * and ciphers goes, another extension to SSL_SUPER and/or SSL_ULTRA would 423 * be possible. 424 */ 425 # define SSL_EXP_MASK 0x00000003L 426 # define SSL_STRONG_MASK 0x000001fcL 427 428 # define SSL_NOT_EXP 0x00000001L 429 # define SSL_EXPORT 0x00000002L 430 431 # define SSL_STRONG_NONE 0x00000004L 432 # define SSL_EXP40 0x00000008L 433 # define SSL_MICRO (SSL_EXP40) 434 # define SSL_EXP56 0x00000010L 435 # define SSL_MINI (SSL_EXP56) 436 # define SSL_LOW 0x00000020L 437 # define SSL_MEDIUM 0x00000040L 438 # define SSL_HIGH 0x00000080L 439 # define SSL_FIPS 0x00000100L 440 # define SSL_NOT_DEFAULT 0x00000200L 441 442 /* we have used 000003ff - 22 bits left to go */ 443 444 /*- 445 * Macros to check the export status and cipher strength for export ciphers. 446 * Even though the macros for EXPORT and EXPORT40/56 have similar names, 447 * their meaning is different: 448 * *_EXPORT macros check the 'exportable' status. 449 * *_EXPORT40/56 macros are used to check whether a certain cipher strength 450 * is given. 451 * Since the SSL_IS_EXPORT* and SSL_EXPORT* macros depend on the correct 452 * algorithm structure element to be passed (algorithms, algo_strength) and no 453 * typechecking can be done as they are all of type unsigned long, their 454 * direct usage is discouraged. 455 * Use the SSL_C_* macros instead. 456 */ 457 # define SSL_IS_EXPORT(a) ((a)&SSL_EXPORT) 458 # define SSL_IS_EXPORT56(a) ((a)&SSL_EXP56) 459 # define SSL_IS_EXPORT40(a) ((a)&SSL_EXP40) 460 # define SSL_C_IS_EXPORT(c) SSL_IS_EXPORT((c)->algo_strength) 461 # define SSL_C_IS_EXPORT56(c) SSL_IS_EXPORT56((c)->algo_strength) 462 # define SSL_C_IS_EXPORT40(c) SSL_IS_EXPORT40((c)->algo_strength) 463 464 # define SSL_EXPORT_KEYLENGTH(a,s) (SSL_IS_EXPORT40(s) ? 5 : \ 465 (a) == SSL_DES ? 8 : 7) 466 # define SSL_EXPORT_PKEYLENGTH(a) (SSL_IS_EXPORT40(a) ? 512 : 1024) 467 # define SSL_C_EXPORT_KEYLENGTH(c) SSL_EXPORT_KEYLENGTH((c)->algorithm_enc, \ 468 (c)->algo_strength) 469 # define SSL_C_EXPORT_PKEYLENGTH(c) SSL_EXPORT_PKEYLENGTH((c)->algo_strength) 470 471 /* Mostly for SSLv3 */ 472 # define SSL_PKEY_RSA_ENC 0 473 # define SSL_PKEY_RSA_SIGN 1 474 # define SSL_PKEY_DSA_SIGN 2 475 # define SSL_PKEY_DH_RSA 3 476 # define SSL_PKEY_DH_DSA 4 477 # define SSL_PKEY_ECC 5 478 # define SSL_PKEY_GOST94 6 479 # define SSL_PKEY_GOST01 7 480 # define SSL_PKEY_NUM 8 481 482 /*- 483 * SSL_kRSA <- RSA_ENC | (RSA_TMP & RSA_SIGN) | 484 * <- (EXPORT & (RSA_ENC | RSA_TMP) & RSA_SIGN) 485 * SSL_kDH <- DH_ENC & (RSA_ENC | RSA_SIGN | DSA_SIGN) 486 * SSL_kEDH <- RSA_ENC | RSA_SIGN | DSA_SIGN 487 * SSL_aRSA <- RSA_ENC | RSA_SIGN 488 * SSL_aDSS <- DSA_SIGN 489 */ 490 491 /*- 492 #define CERT_INVALID 0 493 #define CERT_PUBLIC_KEY 1 494 #define CERT_PRIVATE_KEY 2 495 */ 496 497 # ifndef OPENSSL_NO_EC 498 /* 499 * From ECC-TLS draft, used in encoding the curve type in ECParameters 500 */ 501 # define EXPLICIT_PRIME_CURVE_TYPE 1 502 # define EXPLICIT_CHAR2_CURVE_TYPE 2 503 # define NAMED_CURVE_TYPE 3 504 # endif /* OPENSSL_NO_EC */ 505 506 typedef struct cert_pkey_st { 507 X509 *x509;
