1 Tools to convert the RFC-defined IKE DH groups into OpenSSL and OpenSSH
2 compatible PEM and moduli files that we can distribute.
4 The files in this directory have been generated (as described below) from the
5 RFCs. The PEM files have been compared with the ones in Exim's
6 "std-crypto.c". The OpenSSH moduli files have been checked using `ssh-keygen`
9 Prerequisite: gen_pkcs3 from the Exim sources, which we don't include
10 here due to duplication and licensing issues (ACH is under CC, Exim
13 Limitations: since gen_pkcs3 only supports MODP DH parameters, we
14 don't process the ECP variation.

20 - produce an input file for each group named <group>.txt by copying
