The man page for ssh-keygen(1) has a section "MODULI GENERATION" that describes
how to generate your own moduli file. The following script might also be helpful:
| #! /usr/bin/env bash
|
| moduliFiles=()
|
| generateModuli()
| {
| ssh-keygen -G "moduli-$1.candidates" -b "$1"
| ssh-keygen -T "moduli-$1" -f "moduli-$1.candidates"
| rm "moduli-$1.candidates"
| }
|
| for (( i=0 ; i <= 16 ; ++i )); do
| let bitSize="2048 + i * 128"
| generateModuli "$bitSize" &
| moduliFiles+=( "moduli-$bitSize" )
| done
| wait
|
| echo >moduli "# Time Type Tests Tries Size Generator Modulus"
| cat >>moduli "${moduliFiles[@]}"
| rm "${moduliFiles[@]}"
Note that generating moduli takes a long time, i.e. several hours on a fast
machine!
