otpprint: print lists of one-time passwords


otpprint - print lists of one-time passwords


otp [-n count ] [-e ] [-h ] [-f algorithm ] sequence-number seed


The otp program prints lists of OTPs.

Use this to print out a series of one-time passwords. You will have to supply the sequence number and the seed as arguments and then the program will prompt you for your pass-phrase.

There are several different print formats. The default is to print each password with six short english words.

Options are:

Print the passwords in ``extended'' format. In this format a prefix that says ``hex:'' or ``word:'' is included.
To choose a different algorithm from the default md5. Pick any of: md4, md5, and sha.
Print the passwords in hex.
Print count one-time passwords, starting at sequence-number and going backwards. The default is 10.
