16 History:
18 Modified by cmetz for OPIE 2.4. Added sequence number limits. Added
19 struct opie_otpkey and made many functions use it. Added
20 opiestrncpy(). Include header with libmissing prototypes.
21 Modified by cmetz for OPIE 2.32. Added symbolic flag names for
22 opiepasswd(). Added __opieparsechallenge() prototype.
23 Modified by cmetz for OPIE 2.31. Removed active attack protection.
24 Modified by cmetz for OPIE 2.3. Renamed PTR to VOIDPTR. Added
25 re-init key and extension file fields to struct opie. Added
26 opie_ prefix on struct opie members. Added opie_flags field
27 and definitions. Added more prototypes. Changed opiehash()
28 prototype.
29 Modified by cmetz for OPIE 2.22. Define __P correctly if this file
30 is included in a third-party program.
31 Modified by cmetz for OPIE 2.2. Re-did prototypes. Added FUNCTION
32 definition et al. Multiple-include protection. Added struct
33 utsname fake. Got rid of gethostname() cruft. Moved UINT4
34 here. Provide for *seek whence values. Move MDx context here
35 and unify. Re-did prototypes.
36 Modified at NRL for OPIE 2.0.
37 Written at Bellcore for the S/Key Version 1 software distribution
38 (skey.h).
