 	Important Note
 	The development of ipsec-tools has been ABANDONED.

 	ipsec-tools has security issues, and you should not use it. Please
 	switch to a secure alternative!

There are known unfixed CVEs in that codebase.

While Apple and Android have their own clones of this code for IKEv1,
even basically all 20+ year old IKEv1 clients support the draft 02/03/05
versions that obsoletes the 00/01 draft code.
