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 440 441/* we have used 000001ff - 23 bits left to go */ 442 443/*- 444 * Macros to check the export status and cipher strength for export ciphers. 445 * Even though the macros for EXPORT and EXPORT40/56 have similar names, 446 * their meaning is different: 447 * *_EXPORT macros check the 'exportable' status. 448 * *_EXPORT40/56 macros are used to check whether a certain cipher strength 449 * is given. 450 * Since the SSL_IS_EXPORT* and SSL_EXPORT* macros depend on the correct 451 * algorithm structure element to be passed (algorithms, algo_strength) and no 452 * typechecking can be done as they are all of type unsigned long, their 453 * direct usage is discouraged. 454 * Use the SSL_C_* macros instead. 455 */ 456# define SSL_IS_EXPORT(a) ((a)&SSL_EXPORT) 457# define SSL_IS_EXPORT56(a) ((a)&SSL_EXP56) 458# define SSL_IS_EXPORT40(a) ((a)&SSL_EXP40) 459# define SSL_C_IS_EXPORT(c) SSL_IS_EXPORT((c)->algo_strength) 460# define SSL_C_IS_EXPORT56(c) SSL_IS_EXPORT56((c)->algo_strength) 461# define SSL_C_IS_EXPORT40(c) SSL_IS_EXPORT40((c)->algo_strength) 462 463# define SSL_EXPORT_KEYLENGTH(a,s) (SSL_IS_EXPORT40(s) ? 5 : \ 464 (a) == SSL_DES ? 8 : 7) 465# define SSL_EXPORT_PKEYLENGTH(a) (SSL_IS_EXPORT40(a) ? 512 : 1024) 466# define SSL_C_EXPORT_KEYLENGTH(c) SSL_EXPORT_KEYLENGTH((c)->algorithm_enc, \ 467 (c)->algo_strength) 468# define SSL_C_EXPORT_PKEYLENGTH(c) SSL_EXPORT_PKEYLENGTH((c)->algo_strength) 469 470/* Mostly for SSLv3 */ 471# define SSL_PKEY_RSA_ENC 0 472# define SSL_PKEY_RSA_SIGN 1 473# define SSL_PKEY_DSA_SIGN 2 474# define SSL_PKEY_DH_RSA 3 475# define SSL_PKEY_DH_DSA 4 476# define SSL_PKEY_ECC 5 477# define SSL_PKEY_GOST94 6 478# define SSL_PKEY_GOST01 7 479# define SSL_PKEY_NUM 8 480 481/*- 482 * SSL_kRSA <- RSA_ENC | (RSA_TMP & RSA_SIGN) | 483 * <- (EXPORT & (RSA_ENC | RSA_TMP) & RSA_SIGN) 484 * SSL_kDH <- DH_ENC & (RSA_ENC | RSA_SIGN | DSA_SIGN) 485 * SSL_kEDH <- RSA_ENC | RSA_SIGN | DSA_SIGN 486 * SSL_aRSA <- RSA_ENC | RSA_SIGN 487 * SSL_aDSS <- DSA_SIGN 488 */ 489 490/*- 491#define CERT_INVALID 0 492#define CERT_PUBLIC_KEY 1 493#define CERT_PRIVATE_KEY 2 494*/ 495 496# ifndef OPENSSL_NO_EC 497/* 498 * From ECC-TLS draft, used in encoding the curve type in ECParameters 499 */ 500# define EXPLICIT_PRIME_CURVE_TYPE 1 501# define EXPLICIT_CHAR2_CURVE_TYPE 2 502# define NAMED_CURVE_TYPE 3 503# endif /* OPENSSL_NO_EC */ 504 505typedef struct cert_pkey_st { 506 X509 *x509;
