I'm trying to configure a jetty-distribution-9.3.1.v20150714
backend running on Java 1.8.0_45-b14
with a certificate signed by a self-signed CA certificate, for SSL pinning.
Following Apple's guide, I created a self signed CA certificate, then created a certificate based on that CA cert.
Result is a ServerCertificate.p12
with server's certificate and a private key and a root.cer
file, which will be used for pinning.
$ keytool -list -keystore keystore.p12 -storetype pkcs12
server, Jul 27, 2015, PrivateKeyEntry,
Certificate fingerprint (SHA1): AA:BB:CC.........11:22:33
I've worked before with certs signed by a trusted CAs, so the backend should have SSL configured correctly. The mobile app's pinning framework was tested with a different website self-signed, it works well.
But the app fails to connect with my backend with that keystore: Trust anchor for certification path not found.
I had the feeling the CA cert is missing from the keystore, so I've tried to add it with keytool -import -alias root -keystore keystore.p12 -storetype pkcs12 -trustcacerts -file root.crt
(.crt is a base64 readable certificate file), but it didn't help.
# after adding root.crt
$ keytool -list -keystore keystore.p12 -storetype pkcs12
server, Jul 27, 2015, PrivateKeyEntry,
Certificate fingerprint (SHA1): AA:BB:CC.........11:22:33
root, Jul 27, 2015, trustedCertEntry,
Certificate fingerprint (SHA1): FF:DD:EE.........33:22:11

Interestingly, curl https://example.com --cacert server.cer
works well... (it doesn't without the --cacert)
Any idea what's wrong with the configuration?
