NAME
opiegen - Example OPIE-based OTP generatorSYNOPSIS
opiegen[ challenge ]
DESCRIPTION
opiegen takes a properly formed OTP challenge either from the command line or from standard input, prompts the user for a secret pass phrase, and generates an OTP response to that challenge. It is intended as an example for programmers of how a simple OTP generator can be built. Users should probably use the opiekey program instead.EXAMPLE
wintermute$ opiegen otp-md5 495 wi01309
Secret Pass Phrase:
GILL HUED GOES CHUM LIEU VAIN
wintermute$
BUGS
opiegen(1) can lull a user into revealing his/her password when remotely logged in, thus defeating the purpose of OPIE. This is especially a problem with xterm. opiegen(1) implements simple checks to reduce the risk of a user making this mistake. Better checks are needed.SEE ALSO
