otp(n) RFC 2289 A One-Time Password System otp(n)
__________________________________________________________________________________________________________________________________________________
NAME
otp - One-Time Passwords
SYNOPSIS
package require Tcl 8.2
package require otp ?1.0.0?
::otp::otp-md4 ?-hex? ?-words? -seed seed -count count data
::otp::otp-md5 ?-hex? ?-words? -seed seed -count count data
::otp::otp-sha1 ?-hex? ?-words? -seed seed -count count data
::otp::otp-rmd160 ?-hex? ?-words? -seed seed -count count data
_________________________________________________________________
DESCRIPTION
This package is an implementation in Tcl of the One-Time Password system as described in RFC 2289 (1). This system uses message-digest
algorithms to sequentially hash a passphrase to create single-use passwords. The resulting data is then provided to the user as either
hexadecimal digits or encoded using a dictionary of 2048 words. This system is used by OpenBSD for secure login and can be used as a SASL
mechanism for authenticating users.
In this implementation we provide support for four algorithms that are included in the tcllib distribution: MD5 (2), MD4 (3), RIPE-MD160
(4) and SHA-1 (5).
COMMANDS
::otp::otp-md4 ?-hex? ?-words? -seed seed -count count data
::otp::otp-md5 ?-hex? ?-words? -seed seed -count count data
::otp::otp-sha1 ?-hex? ?-words? -seed seed -count count data
::otp::otp-rmd160 ?-hex? ?-words? -seed seed -count count data
EXAMPLES
% otp::otp-md5 -count 99 -seed host67821 "My Secret Pass Phrase"
(binary gibberish)
% otp::otp-md5 -words -count 99 -seed host67821 "My Secret Pass Phrase"
SOON ARAB BURG LIMB FILE WAD
% otp::otp-md5 -hex -count 99 -seed host67821 "My Secret Pass Phrase"
