windows default keyfile location is
%APPDATA%\postgresql\root.crt

this can be overridden by environment variables.

@earthman
It would be great to get kind personal guide, not just link, could you explain in some kind step by step ?, I have downloaded OpenSSL 1.0 Beta and what should I do now ?, please understand that I'm still new in SSL matter
Regards

@earthman
Is Postgresql really has native SSL integrated without have to install OpenSSL ?

 

by: gheistPosted on 2009-09-07 at 13:56:59ID: 25277243

Screenshot from EnterpriseDB 8.4 on Vista Ultimate SP2 - it has all the SSL libraries - no recompile needed.
It can be overridden with system-wide openssl installation if there is some security issue, but that is not needed.

@gheist
please be more elaborate :(

 

by: gheistPosted on 2009-09-07 at 16:20:06ID: 25277803

First two libraries linked from postgresql's main executable compose OpenSSL toolkit's server and client side.
You can run dependency walker yourself to see if same applies to your setup.

@gheist
you mean I just have to copy SSLEAY32.DLL and LIBEAY32.DLL files ?

then what about @earthman2 said with .crt files ?

I really confused now :(

 

by: gheistPosted on 2009-09-08 at 15:19:46ID: 25286647

1) you check that postgresql is linked against two ssl libraries
2) if it is linked against ssl libraries it supports all the crt stuff earthman is talking about.

@gheist
how about the key ?, is it suppose to has some sort a key right ?, I mean to acknowledge between client app and database.

Ask your favorite search engine about "generate self-signed certificate using openssl"

 

by: MunggaranPosted on 2009-09-10 at 07:03:43ID: 25300304

it seems postgresql already generated one, but to test it I have change postgresql.conf :

ssl = on                        # (change requires restart)
ssl_ciphers = 'ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH'      # allowed SSL ciphers
                              # (change requires restart)
password_encryption = on

so it will accept SSL connection, but then when I test with my application, it still can connect using no ssl. Is there anyway to make postgresql ONLY accept ssl connection ?

 

by: gheistPosted on 2009-09-11 at 04:16:28ID: 25308213

There is no way - all listen ports are duplex
password encryption is not relevant for ssl communication. it is whether passwords go encryppted into system database.
