Removed active attack protection. 1922347Spst Modified by cmetz for OPIE 2.3. Renamed PTR to VOIDPTR. Added 2022347Spst re-init key and extension file fields to struct opie. Added 2122347Spst opie_ prefix on struct opie members. Added opie_flags field 2222347Spst and definitions. Added more prototypes. Changed opiehash() 2322347Spst prototype. 2422347Spst Modified by cmetz for OPIE 2.22. Define __P correctly if this file 2522347Spst is included in a third-party program. 2622347Spst Modified by cmetz for OPIE 2.2. Re-did prototypes. Added FUNCTION 2722347Spst definition et al. Multiple-include protection. Added struct 2822347Spst utsname fake. Got rid of gethostname() cruft. Moved UINT4 2922347Spst here. Provide for *seek whence values. Move MDx context here 3022347Spst and unify. Re-did prototypes. 3122347Spst Modified at NRL for OPIE 2.0. 3222347Spst Written at Bellcore for the S/Key Version 1 software distribution 3322347Spst (skey.h). 3422347Spst*/ 3522347Spst#ifndef _OPIE_H 3629967Sache#define _OPIE_H 1 3722347Spst 3822347Spststruct opie { 3922347Spst int opie_flags; 4022347Spst char opie_buf[256]; 4122347Spst char *opie_principal; 4222347Spst int opie_n; 4322347Spst char *opie_seed; 4422347Spst char *opie_val; 4522347Spst long opie_recstart; 4622347Spst}; 4722347Spst 4822347Spst#define __OPIE_FLAGS_RW 1 4922347Spst#define __OPIE_FLAGS_READ 2 5022347Spst 5122347Spst/* Minimum length of a secret password */ 5222347Spst#define OPIE_SECRET_MIN 10 5322347Spst 5422347Spst/* Maximum length of a secret password */ 5522347Spst#define OPIE_SECRET_MAX 127 5622347Spst 5722347Spst/* Minimum length of a seed */ 5822347Spst#define OPIE_SEED_MIN 5 5922347Spst 6022347Spst/* Maximum length of a seed */ 6122347Spst#define OPIE_SEED_MAX 16 6222347Spst 6322347Spst/* Maximum length of a challenge (otp-md? 9999 seed) */ 6422347Spst#define OPIE_CHALLENGE_MAX (7+1+4+1+OPIE_SEED_MAX) 6522347Spst 6622347Spst/* Maximum length of a response that we allow */ 6722347Spst#define OPIE_RESPONSE_MAX (9+1+19+1+9+OPIE_SEED_MAX+1+19+1+19+1+19) 6822347Spst 6922347Spst/* Maximum length of a principal (read: user name) */ 7022347Spst#define OPIE_PRINCIPAL_MAX 32 7122347Spst 7229967Sache#include <sys/cdefs.h> 7322347Spst 7423540Spst__BEGIN_DECLS 7522347Spstint opieaccessfile __P((char *)); 7622347Spstint rdnets __P((long)); 7722347Spstint isaddr __P((register char *)); 7822347Spstint opiealways __P((char *)); 7922347Spstchar *opieatob8 __P((char *,char *)); 8023540Spstvoid opiebackspace __P((char *)); 8122347Spstchar *opiebtoa8 __P((char *,char *)); 8222347Spstchar *opiebtoe __P((char *,char *)); 8322347Spstchar *opiebtoh __P((char *,char *)); 8422347Spstint opieetob __P((char *,char *)); 8522347Spstint opiechallenge __P((struct opie *,char *,char *)); 8622347Spstint opiegenerator __P((char *,char *,char *)); 8722347Spstint opiegetsequence __P((struct opie *)); 8823540Spstvoid opiehash __P((void *, unsigned)); 8922347Spstint opiehtoi __P((register char)); 9022347Spstint opiekeycrunch __P((int, char *, char *, char *)); 9122347Spstint opielock __P((char *)); 9222347Spstint opielookup __P((struct opie *,char *)); 9322347Spstint opiepasscheck __P((char *)); 9423540Spstvoid opierandomchallenge __P((char *)); 9522347Spstchar * opieskipspace __P((register char *)); 9623540Spstvoid opiestripcrlf __P((char *)); 9722347Spstint opieverify __P((struct opie *,char *)); 9829967Sacheint opiepasswd __P((struct opie *, int, char *, int, char *, char *)); 9922347Spstchar *opiereadpass __P((char *, int, int)); 10022347Spstint opielogin __P((char *line, char *name, char *host)); 10123540Spst__END_DECLS 10222347Spst 10329967Sache#if _OPIE 10429967Sache#define VOIDPTR void * 10529967Sache#define VOIDRET void 10629967Sache#define NOARGS void 10729967Sache#define FUNCTION(arglist, args) (args) 10829967Sache#define AND , 10929967Sache#define FUNCTION_NOARGS () 11029967Sache#define UINT4 u_int32_t 11123540Spst 11223540Spst__BEGIN_DECLS 11322347Spststruct utmp; 11429967Sacheint __opiegetutmpentry __P((char *, struct utmp *)); 11522347Spst#ifdef EOF 11622347SpstFILE *__opieopen __P((char *, int, int)); 11729967Sache#endif /* EOF */ 11829967Sacheint __opiereadrec __P((struct opie *)); 11929967Sacheint __opiewriterec __P((struct opie *)); 12029972Sache__END_DECLS 12129967Sache#endif /* _OPIE */ 12222347Spst#endif /* _OPIE_H */ 123
