[stunnel-users] fips=no

Hello,

As I understand it this is just a compliance mode.
Compliance with the FIPS 140-2 U.S. standard
http://en.wikipedia.org/wiki/FIPS_140-2

In some cases, I assume you might be required to run a FIPS 140-2 compliant 
setup. In which case your cryptographic libraries should be certified. AND
there are some changes in configuration such as disabling non-fips approved
ciphers and mac algorithms
Example: Under FIPS mode MD5 and RC4 are not used. 
Then you can tell the gov. or whoever is asking you that you are following 
FIPS. 

You can potentially achieve the same without having to enable FIPS.
Just enable strong ciphers, disable MD5,RC4,SSLv2 etc. It is all
outlined in the document.

I run stunnel at home and for personal use, so I have never had to do deep
research into this, so this is my general understanding. If anyone
would like to share a more complete answer that would be even better.

Thanks

Hi All,

I have the problem that when I start Stunnel, the following error pops up:

FIPS_mode_set: 2D06C06E: error:2D06C06E:FIPS routines:FIPS_mode_set:fingerprint 
does not match

I now added in my config file: fips=no and it works.

My question is now, what is the difference between with fips and without fips?

stunnel version 4.34
openssl 0.9.8
redhat 5

Thanks in advance for the answer

Regards

Dominic
