Hello stunnel users,
I'm trying to compile stunnel 4.56 with FIPS support on Ubuntu 12.04. Always end up with the infamous "fingerprint does not match" error. I can't figure out what I'm doing wrong.
1. Download openssl-fips-2.0.2.tar.gz, unpack, ./config, make, and sudo make install (as specified in http://www.openssl.org/docs/fips/UserGuide-2.0.pdf)
2. Download openssl-1.0.1e.tar.gz, unpack, ./config fips --with-fipslibdir=/usr/local/ssl/fips-2.0/lib/ --with-fipsdir=/usr/local/ssl/fips-2.0/, make depend, make, and sudo make install
3. At this point, openssl is working in FIPS mode: > OPENSSL_FIPS=1 /usr/local/ssl/bin/openssl version OpenSSL 1.0.1e-fips 11 Feb 2013
> OPENSSL_FIPS=1 /usr/local/ssl/bin/openssl sha1 c_rehash SHA1(c_rehash)= 5af9e1479950bbbd9d3304c181b3f802c54f64fd
> OPENSSL_FIPS=1 /usr/local/ssl/bin/openssl md5 c_rehash Error setting digest md5 139806582736544:error:060A80A3:digital envelope routines:FIPS_DIGESTINIT:disabled for fips:fips_md.c:180:
4. Download stunnel-4.56.tar.gz, unpack, ./configure --enable-fips --with-ssl=/usr/local/ssl, make, and sudo make install
5. While configuring and building stunnel completes as expected, the following does appear in ./configure's output:
checking whether to enable FIPS mode support... yes configure: **************************************** SSL checking for SSL directory... /usr/local/ssl checking /usr/local/ssl/include/openssl/engine.h usability... yes checking /usr/local/ssl/include/openssl/engine.h presence... yes checking for /usr/local/ssl/include/openssl/engine.h... yes checking /usr/local/ssl/include/openssl/ocsp.h usability... yes checking /usr/local/ssl/include/openssl/ocsp.h presence... yes checking for /usr/local/ssl/include/openssl/ocsp.h... yes checking /usr/local/ssl/include/openssl/fips.h usability... no checking /usr/local/ssl/include/openssl/fips.h presence... no checking for /usr/local/ssl/include/openssl/fips.h... no configure: WARNING: OpenSSL fips header not found
This is not entirely unexpected as fips.h only exists in /usr/local/ssl/fips-2.0/include/openssl.
6. Running stunnel however fails:
> /usr/local/bin/stunnel Clients allowed=500 stunnel 4.56 on x86_64-unknown-linux-gnu platform Compiled/running with OpenSSL 1.0.1e-fips 11 Feb 2013 Threading:PTHREAD Sockets:POLL,IPv6 SSL:ENGINE,OCSP,FIPS Reading configuration from file /usr/local/etc/stunnel/stunnel.conf FIPS_mode_set: 2D06B06F: error:2D06B06F:FIPS routines:FIPS_check_incore_fingerprint:fingerprint does not match Line 61: "[pop3s]": Failed to initialize SSL str_stats: 5 block(s), 120 data byte(s), 290 control byte(s)
I can't figure out what's causing this, hoping someone on the list may have a couple suggestions. Thanks in advance!
