I am trying to connect pgAdmin to digitalOcean. However I am getting this error:
I add the certificate but digital ocean didn't provided me a key file.
Where could I find it?
This Is how I add the certificate file.
Thank you,
Jonathan Prieto
I think that the certificate that DigitalOcean provided is for the “Root certificate” field.
It is to verify the server, not to authenticate the client.
With the default configuration of libpq you don't need the certificate at all, and SSL is used only to encrypt the communication.
You need to create this private key with openssl command.
Unfortunately client certificate setup is not documented in the PostgreSQL official documentation.
The best documentation that I have found is the following:
https://info.crunchydata.com/blog/ssl-certificate-authentication-postgresql-docker-containers.
You should try to adapt "Step 4: Generating the Client Key and Certificate" to your configuration.

I have configured Opensearch with valid SSL certifcate ( PKCS ).I have made entry in opensearch.yml with all required entries according to documentation .Also imported certificate in Opensearch server(internal jdk) and calling app (client side) but opensearch throws cert_unknown error when calling API. Please help if someone knows what enries need to be in opensearch.yml.If some one can share steps to setup multi-node setup with SSL with selfsigned certificate will also be great help.
Does AWS DocumentDB support authenticating clients with SSL?I've downloaded rds-combined-ca-bundle.pem and got rds-truststore.jks by following the aws link "https://docs.aws.amazon.com/documentdb/latest/developerguide/connect_programmatically.html#connect_programmatically-tls_enabled".Specifying it in truststore,I can successfully connect to document db.
For two way ssl,I've created keystore using self-signed certificate following the link https://docs.mongodb.com/manual/appendix/security/appendixA-openssl-ca/. I'm able to connect to documentdb by specifying any keystore,even by specifying rds-truststore.jks in both truststore and keystore also.
Amazon DocumentDB doesn't support x509 certificate based authentication, only username/password authentication.
As the service is continually improving, stay tuned for new releases .
We want to connect the PostgreSQL db through jdbc using the self signed certificate. Keystore option is available but i want to pass the certificate though my jdbc command line . is there any option available for the same
According to the documentation, the URL will look somewhat like this:
jdbc:postgresql://host:port/database?ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory&sslcert=/path/to/cert&sslkey=/path/to/key
This assumes that the client doesn't need to verify the server's certificate, but the server will verify the client's certificate.
the sslmode if set to require, will not verify the CA cert or hostname. it is best fit for self signed cert. No need keystore.
jdbc:postgresql://host:port/database?ssl=true&sslmode=require
If you want to verify the CA, can do it like:
jdbc:postgresql://host:port/database?ssl=true&sslmode=verify-full&sslrootcert=/my-path/hey.pem
Good day,
My web application need to connect to IBM third party to get some response. Thus, IBM give me a .p12 file which contain of client certificate.
At first I import this .p12 file into my existing CellDefaultKeyStore, and it will hit certificate chain error.
com.ibm.jsse2.util.j: PKIX path building failed: java.security.cert.CertPathBuilderException: PKIXCertPathBuilderImpl could not build a valid CertPath.; internal cause is:
java.security.cert.CertPathValidatorException: The certificate issued by xxx is not trusted; internal cause is:
java.security.cert.CertPathValidatorException: Certificate chaining error
Then I go import this .p12 file into NodeDefaultKeyStore, and surprisingly its work. My application able to call to the third party and get reponse code 200.
I am not understand how to explain to my client on this.
As my understanding, management scope in CellDefaultKeyStore is bigger because its in cell, NodeDefaultKeyStore should consider part of cell only, suppose CellDefaultKeyStore should work.
Anyone can advise on this?
Just to shortly explain few concepts:
CellDefaultTrustStore - is store for signer certificates, for the servers that you connect to, to be trusted. It is shared by all the nodes and servers by default
NodeDefaultKeyStore - is store for private certs, so the certs that are used for client authentication. Each node by default has its own store and private cert to authenticate.
CellDefaultKeyStore - is store for private certs associated with the cell. Used by deployment manager, not nodes serving apps. It is NOT used by federated nodes.
NodeDefaultSSLSettings - this manages SSL config for the given node, you can check it. By default it is using NodeDefaultKeyStore (not CellDefaultKeyStore), and CellDefaultTrustStore
But back to your question.
If you need to connect to some service using client certificate authentication, what you should do is:
create new keystore with cert from the p12 file
create new truststore with all signer certs required to connect to that service
create new SSL Config that will point to these stores
create Dynamic outbound endpoint SSL configuration settings, pointing to your ssl config, select correct client cert, and specify connection info in the form protocol,host,port
This configuration will be picked up when you will be doing outbound ssl connection that matches info you entered.
I'm receiving the following error when connecting to an AWS Postgres database that requires SSL. I recently upgraded from npgsql 2.3.2 (which was buggy) to 3.0.3 which won't connect. Any suggestions would be appreciated.

I was able to fix the issue by installing the Amazon RDS public certificate on my machine. Once I did this, I was able to connect.
Steps I followed:
Download the AWS RDS public certificate 1
Create a .crt file from the .pem file downloaded. Sample instructions
here 2
Install the certificate (.crt file) on the machine. 3
Connect!
The docs from npgsql give the solution as changing the default trust server certificate of 'false' to 'true' in the connection string.
Unfortunately, neither Excel (AFAIK) nor Power BI will allow you to edit the connection string. So if you are unable to get the SSL certificate from the DB admin (as suggested in another answer), or the SSL cert has a different server name to the name you connect to (in my case an IP address), there is not much that can be done.
I can see two ways of fixing this. Either Shay & co from npgsql (who are doing an excellent job btw) provide some way for users to change the default settings for the connection string parameters. Or Microsoft allows users to send keywords in the connection dialog of Power BI (and Excel).
Npgsql 2.x didn’t perform validation on the server’s certificate by default, so self-signed certificate were accepted. The new default is to perform validation, which is probably why your connection is failing. Specify the Trust Server Certificate connection string parameter to get back previous behavior.
You can read more on the Npgsql security doc page, note also that this change is mentioned in our migration notes.
I had the same issue connecting PowerBI to a locally hosted PostgreSQL server and it turned out to be easy to solve if you can get the right information. Recent Npgsql versions will only connect over SSL if it trusts the certificate of the server. As a Windows application PowerBI uses the windows certificate store to decide what to trust. If you can get the SSL cert for the PostgreSQL server (or the CA cert used to sign that one) then tell Windows to trust that certificate, PowerBI will trust it too.
In the configuration folder for the PostgreSQL server there is a postgresql.conf file, search it for ssl settings, there is one with the location of the ssl cert. Note NOT the key file which contains the private key, only the cert file which contains the public key. copy it or its content to the machine running PowerBI and import using Run | mmc | Add Plugin... Certificates (Google it)
Look at the server name once you imported the cert and connect from PowerBI using the same server name (so the cert matches the connection). That solved the problem for me. If PostgreSQL is configured to insist on a SSL connection you might have to do the same for a ODBC connection too.
Its not best way but worked for me since if u dont need encryption for security reason.
Go to Postgres config file on your DB server and go from
ssl = true
to
ssl = false
Then open your power bi desktop File-> Options and settings -> Data source settings -> then in global you will have saved your connection press Edit Permissions and uncheck "ENCRYPT CONNECTIONS"
Then it will work
WARNING: THIS IS NOT RECOMMENDED IF YOUR DB IS OPEN TO PUBLIC.
