Hi

I am running a windows instance of stunnel as a client and A Linux version as the server When I set this on the Windows side : engine = capi and this in my section:

engineId = capi

I get an error message that CApath or CAFile still needs to be set. My understanding is that these setting should make stunnel use the Windows certificate store to find a root and intermediate certificate to authenticate my (Symantec generated) certificate and should not require a CAfile.

Here is my windows config : ; ************************************************************************** ; * Global options * ; **************************************************************************

; Debugging stuff (may be useful for troubleshooting) debug = debug ;output = stunnel.log

; Enable FIPS 140-2 mode if needed for compliance ;fips = yes

; Microsoft CryptoAPI engine allows for authentication with private keys ; stored in the Windows certificate store ; Each section using this feature also needs the "engineId = capi" option engine = capi

[FIX] client = yes accept = 9021 connect = fixuat.au.abnamroclearing.com:9443http://fixuat.au.abnamroclearing.com:9443 cert = C:\certs\jim.howland.cer key = C:\certs\jim.howland.key verify = 3 ; CAfile = C:\certs\veriSign_root_certificates\symantec-class3-G5.cer engineId = capi

and here is the error [ ] Cron thread initialized [ ] No limit detected for the number of clients [.] stunnel 5.31 on x86-pc-msvc-1500 platform [.] Compiled/running with OpenSSL 1.0.2g-fips 1 Mar 2016 [.] Threading:WIN32 Sockets:SELECT,IPv6 TLS:ENGINE,FIPS,OCSP,PSK,SNI [ ] errno: (*_errno()) [ ] GUI message loop initialized [.] Reading configuration from file stunnel.conf [.] UTF-8 byte order mark detected [ ] Enabling support for engine "capi" [ ] Initializing engine #1 (capi) [ ] Engine #1 (capi) initialized [.] FIPS mode disabled [ ] Compression disabled [ ] Snagged 64 random bytes from C:/.rnd [ ] Wrote 0 new random bytes to C:/.rnd [ ] PRNG seeded successfully [ ] Initializing service [FIX] [!] Service [FIX]: Either "CAfile" or "CApath" has to be configured

Any ideas?
