NAME
otpcalc - An OTP and S/Key calculator for X

SYNOPSIS
otpcalc

DESCRIPTION
otpCalc generates one time passwords for responding to S/Key (RFC1760) and OTP (RFC2289) challenges. It supports MD4, MD5, RIPEMD-160 and SHA1 message digests.

otpCalc determines which message digest to use based on the prefix to the Challenge input:

    s/key | MD5
    otp-md4 | MD4
    otp-md5 | MD5
    otp-rmd160 | RIPEMD-160
    otp-sha1 | SHA1

In the absence of a prefix, the default hash, specified in the Settings menu, is used.
