+The following is an up-to date list of SHA-1 and SHA-256 fingerprints of all
+X.509 certificates Fripost uses on its publicly available services.  Please
+consider any mismatch as a man-in-the-middle attack, and let us know
+immediately! -- admin@fripost.org

+
+    wiki.fripost.org:443 (wiki)
+    SHA1   96:4E:77:71:F3:2B:C7:60:50:58:37:53:C4:B1:F1:50:95:69:FD:C0
+    SHA256 D0:02:01:81:03:86:F3:53:8A:BA:DE:7D:07:D5:E0:31:D8:5B:5D:35:72:BC:68:8B:E4:BF:86:33:42:43:21:90
+
+    git.fripost.org:443 (git server and its web interface)
+    SHA1   EA:50:38:19:38:6A:49:BF:5D:3C:4D:04:64:6F:0D:D3:AC:20:76:C2
+    SHA256 08:D9:18:05:A3:F5:B6:8E:20:81:E1:8A:36:1B:44:AD:4E:36:6D:D1:BA:FC:3D:26:F9:F5:4B:68:A9:0F:F3:21
+
+    antilop.fripost.org:443 (list manager)
+    SHA1   6F:1A:3B:0F:2C:5A:BC:33:09:C6:D4:F8:43:2C:07:6E:B0:FD:DB:7B
+    SHA256 FA:AC:E2:4C:C7:DD:D8:A6:24:20:0E:48:FC:91:D2:F0:CC:BD:BD:57:B1:F9:67:84:73:96:F1:90:4C:50:C1:F1
+
+
+If you want to retrieve the whole certificate, you can run
+
+    openssl s_client -connect imap.fripost.org:993 </dev/null
+
+(For protocols using the STARTTLS directive such as SMTP, you'll have to call
+s_client with '-starttls smtp'.  Other useful options are '-showcerts', which
+prints the whole server certificate chain.)
+
+You'll find the X.509 certificate wrapped between
+
+    -----BEGIN CERTIFICATE-----
+    [...]
+    -----END CERTIFICATE-----
+
+If you store it into /path/to/certificate.pem, you can then ensure that its
+fingerprint matches that above:
+
+    openssl x509 -in /path/to/certificate.pem -noout -fingerprint -sha1
+    openssl x509 -in /path/to/certificate.pem -noout -fingerprint -sha256
+
+Alternatively, using a pipe:
+
+    openssl s_client -connect imap.fripost.org:993 </dev/null \
+    | openssl x509 -noout -fingerprint -sha256
