>Synopsis: skey command does not display all possible one-time passwords
>Category: user
>Environment:
System : OpenBSD 7.5
Details : OpenBSD 7.5-current (GENERIC.MP) #207: Mon Jul 22
21:40:56 MDT 2024
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
You can't display all (from 0 to SKEY_MAX_SEQ (10000)) one-time passwords
with the skey, otp-md5, otp-rmd160 or otp-sha1 commands.
>How-To-Repeat:
$ skey -p coucou -n 9999 10000 plop | head -n 3
2: NAME ECHO FOUR ALL SAP RAT
3: DOE GYP COCA KURT ELY NIBS
4: WEE AIDA DAM COIL GRUB MINK
but
$ skey -p coucou -n 10000 10000 plop | head -n 3
usage: skey [-x] [-md5 | -rmd160 | -sha1] [-n count]
[-p passphrase] <sequence#>[/] key
>Fix:
Line 63 of usr.bin/skey/skey.c, I think it's not:
cnt = strtonum(argv[i], 1, SKEY_MAX_SEQ -1, &errstr);
but
cnt = strtonum(argv[i], 1, SKEY_MAX_SEQ +1, &errstr);
Which results in:
$ ./my_skey -p coucou -n 10001 10000 plop | head -n 3
0: ARM MESH SOUL SELF LADY EDGE
1: IBIS GALL DAME GAB DAYS BITE
2: NAME ECHO FOUR ALL SAP RAT
