Package: otp (970425-3)

Generator for One Time Passwords

otp creates key and password lists for verification and security purposes in a variety of formats. Keys can be of any length, consist of digits or letters (capital or lower case), and alphabetic passwords can either be entirely random (most secure) or obey the digraph statistics of En- glish text (easier to remember when transcribing, but less secure).

For computer applications, for example one-time login passwords, otp can create a file containing the MD5 signa- ture of each of the generated keys. This permits the com- puter to verify keys without the need to store the keys in plaintext.
