SkeyCalc computes one-time passwords for use in logging in to servers which implement OTP (sometimes called S/Key or SKey) access control. SkeyCalc supports both MD4 and MD5 based OTP algorithms. (SkeyCalc isn’t an arithmetic calculator like your pocket calculator.)
SkeyCalc operates as a service, allowing for lightning-fast OTP authentication. It saves your password in Apple’s secure keychain (if you desire). SkeyCalc uses sensitive regular expressions to make using one-time passwords a snap. SkeyCalc is the MacOS X equivalent of opie, opiecalc and skey+.
