3SSL regression tests
4====================
5
6This directory contains a test suite for SSL support. It tests both
7client-side functionality, i.e. verifying server certificates, and
8server-side functionality, i.e. certificate authorization.
9
10CAUTION: The test server run by this test is configured to listen for
11TCP connections on localhost. Any user on the same host is able to
12log in to the test server while the tests are running. Do not run this
13suite on a multi-user system where you don't trust all local users!
14
15Running the tests
16=================
17
18NOTE: You must have given the --enable-tap-tests argument to configure.
19
20Run
21 make check
22or
23 make installcheck
24You can use "make installcheck" if you previously did "make install".
25In that case, the code in the installation tree is tested. With
26"make check", a temporary installation tree is built from the current
27sources and then tested.
28
29Either way, this test initializes, starts, and stops a test Postgres
30cluster that is accessible to other local users!
31
32Certificates
33============
34
35The test suite needs a set of public/private key pairs and certificates to
36run:
37
38root_ca
39 root CA, use to sign the server and client CA certificates.
40
41server_ca
42 CA used to sign server certificates.
43
44client_ca
45 CA used to sign client certificates.
46
47server-cn-only
48server-cn-and-alt-names
49server-single-alt-name
50server-multiple-alt-names
51server-no-names
52 server certificates, with small variations in the hostnames present
53 in the certificate. Signed by server_ca.
54
55server-ss
56 same as server-cn-only, but self-signed.
57
58server-password
59 same as server-cn-only, but password-protected.
60
61client
62 a client certificate, for user "ssltestuser". Signed by client_ca.
63
64client-revoked
65 like "client", but marked as revoked in the client CA's CRL.
66
67In addition, there are a few files that combine various certificates together
68in the same file:
69
70both-cas-1
71 Contains root_ca.crt, client_ca.crt and server_ca.crt, in that order.
72
73both-cas-2
74 Contains root_ca.crt, server_ca.crt and client_ca.crt, in that order.
75
76root+server_ca
77 Contains root_crt and server_ca.crt. For use as client's "sslrootcert"
78 option.
79
80root+client_ca
81 Contains root_crt and client_ca.crt. For use as server's "ssl_ca_file".
82
83client+client_ca
84 Contains client.crt and client_ca.crt in that order. For use as client's
85 certificate chain.
86
87There are also CRLs for each of the CAs: root.crl, server.crl and client.crl.
88
89For convenience, all of these keypairs and certificates are included in the
90ssl/ subdirectory. The Makefile also contains a rule, "make sslfiles", to
91recreate them if you need to make changes.
92
93TODO
94====
95
96* Allow the client-side of the tests to be run on different host easily.
97 Currently, you have to manually set up the certificates for the right
98 hostname, and modify the test file to skip setting up the server. And you
99 have to modify the server to accept connections from the client host.
100
101* Test having multiple server certificates, so that the private key chooses
102 the certificate to present to clients. (And the same in the client-side.)
