Subject [users@httpd] Pass Phrase encrypted private key and certificate and FIPS enabled mod_ssl
Date Wed, 29 Aug 2012 19:45:29 GMT

Last week I posted a message that I had problem with FIPS enabled openssl and httpd v2.4.3.
I did a little bit test today and here is what I found. The original key and certificate was
generated by openssl without FIPS enabled and the key was encrypted by AES 256. When I started
httpd, it prompted me for the pass phrase. I typed in correct pass phrase but it kept prompting
me that the pass phrase is not correct. If I disable FIPS for the mod_ssl, I don't have problem
to provide the same pass phrase and start httpd.

I striped out the pass phrase from the original private key without any other changes and
I can start httpd with FIPS enabled mod_ssl no problem.

I recreated private key with AES 256 encrypted and a pass phrase (I have to provide a pass
phrase) with FIPS enabled OpenSSL (v1.0.1c) and regenerated the certificate from my CA. 

When I started httpd, I got pass phrase prompt and I provided the correct pass phrase and
it says the pass phrase is incorrect.

My question is whether FIPS enabled mod_ssl supports pass phrase? It seems to me it does not.
