NAME
ntp-keygen - generate public and private keys
SYNOPSIS
ntp-keygen [ -deGgHIMnPT ] [ -c [RSA-MD2 | RSA-MD5 | RSA-SHA | RSA-SHA1 | RSA-MDC2 | RSA-RIPEMD160 | DSA-
SHA | DSA-SHA1 ] ] [ -i name ] [ -p password ] [ -S [ RSA | DSA ] ] [ -s name ] [ -v nkeys ]
DESCRIPTION
This program generates cryptographic data files used by the NTPv4 authentication and identification
schemes. It generates MD5 key files used in symmetric key cryptography. In addition, if the OpenSSL
software library has been installed, it generates keys, certificate and identity files used in public key
cryptography. These files are used for cookie encryption, digital signature and challenge/response
identification algorithms compatible with the Internet standard security infrastructure.
