PROGRAM:

NAME


donkey - alternative for S/KEY's "key" command.

SYNOPSIS


donkey [options] sequence seed
donkey -i

key [option] sequence seed
key -i

DESCRIPTION


This manual page documents briefly the donkey, and key commands. This manual page was
written for the Debian GNU/Linux distribution because the original program does not have a
manual page. Instead, it has documentation in /usr/share/doc/donkey

donkey is an alternative for S/KEY's "key" command. The new feature that the original key
doesn't have is print an entry for skeykeys as follows;

kazu 0099 al02004 115d83956f1089b6 Apr 26,1995 22:13:27

This means that donkey is also an alternative for "keyinit". Since the entry is printed to
stdout (not to /etc/skeykeys), you can easily sent it to a remote operator by e-mail (with
a PGP signature or something). So it is possible to initiate S/KEY without loginging onto
the console of the host.

OPTIONS


A summary of options is included below.

-n num specify the number of keys to be calculated.

-f func choose a hash function - one of MD2 , MD4 , or MD5

EXAMPLES


(1) Calculate an One-Time-Password.
Execute Donkey with a sequence number and a seed, then input your passphrase.

% donkey 80 is12345
Enter passphrase : xxx
SOFT O SAW SWAB CON RODE

You can choose the hash function.

% donkey 80 is12345
Enter passphrase : xxx
SOFT O SAW SWAB CON RODE

%donkey -f md5 80 is12345
Enter passphrase : xxx
LACK WIN ROSE ANNA STUN REEK

The default hash function is MD4 due to historical reasons.

(2) Calculate several One-Time-Passwords at once.
Use the -n option.

% donkey -n 10 80 is12345
Enter passphrase : xxx
71: WORE HELL CUB FAR DORA MALE
72: SAIL DAN DONE BEER DAYS MOS
73: PAN TONE THAT TOUT BURY EST
74: KEN ROAM HEAT NAN MEAN HEN
75: MINI MARS HASH BOTH SITU SING
76: TOW SHIN FLUE ARID AHOY NE
77: SLID LEEK NO TREE STOW BEY
78: RUDY WINE GIFT FUSS AGEE SUE
79: GELD THIN MAID THIN BUD TURF
80: SOFT O SAW SWAB CON RODE

Note that though "Enter passphrase" is printed out to the standard erorr stream, the One-
Time-Passwords are written to the standard output stream, so you can redirect the output
safely.

(3) Print an skeykeys entry.
Use the -i option without argments. Then, enter the login name, the sequence number and
the seed. Input your passphrase twice to get the entry.

% donkey -i
Enter login name [default kazu]:
Enter sequence 1 to 999 [default 99]:
Enter new seed [default ur18122]:
Please choose passphrase between 8 and 256 characters.
Enter passphrase : xx
Re-enter passphrase : xx
