authspeed - determine authentication delays


authspeed [ -cdm ] [ -n loops ] auth.samplekeys


This program encrypts a test file and determines the authentication delay to use in the NTP configuration file. There are two choices of encryption algorithm, DES Cipher-Block-Chaining (DES-CBC) and Message Digest 5 (MD5).


Select total cost of encryption. Default is value to use in the authdelay configuration command.

Enable debug output. Default is no debug output.

Enable MD5 algorithm. Default is DES-CBC algorithm.

-n loops
Specify the number of program loops. Default is 20,000.
