Hi

thanks for all the comments and suggestions, especially the ones I could understand

centos 7
yum upgrade

openssl version gives:

OpenSSL 1.0.2k-fips  26 Jan 2017


it looks like

echo 'LegacySigningMDs md5' >> /etc/pki/tls/legacy-settings

allows the reading of Md5 Client certificates (which are still being installed in "not released yet" phones)

I am almost concerned this is being done intentionally to meet some security downgrade requirement. I the more reason to only use this cert to bootstrap your own cert for the actual management.



That is a week of my life I wont get back

thanks again

Stuart

I don't know offhand which OpenSSL versions did away with MD5, but you
*can* install an 0.9.8e (+ RHEL/CentOS backported security patches)
straight off CentOS 7 repos:

Ugh. No need for 0.9.8e (which is from, what, the early Industrial Revolution?). MD5 is still available in OpenSSL 1.0.2, assuming it wasn't disabled in the build configuration. I think Stuart is dealing with an OpenSSL build that had MD5 disabled in the Configure step.

Heck, MD4 and MDC2 are still available in 1.0.2 - even with the default configuration, I believe. I'm looking at 1.0.2j here and it has GOST, MD4, MD5, MDC2, RIPEMD-60, SHA, SHA1, SHA-2 (all standard lengths), and Whirlpool.

That's just for digests, obviously; but the point is the MD5 support is still there. And yes, 1.0.2j can handle certificates with md5WithRsaEncryption signatures.
