Is there any way to allow only https, instead of http, for the communication with the Neo4j server? Also, which channel does the Neo4j Shell's communication use, http or https?
This is from Neo4j Documentation:
HTTPS support
The Neo4j server includes built in support for SSL encrypted communication over HTTPS. The first time the server starts, it automatically generates a self-signed SSL certificate and a private key. Because the certificate is self signed, it is not safe to rely on for production use, instead, you should provide your own key and certificate for the server to use.
To provide your own key and certificate, replace the generated key and certificate, or change the neo4j-server.properties file to set the location of your certificate and key:
# Certificate location (auto generated if the file does not exist)
org.neo4j.server.webserver.https.cert.location=ssl/snakeoil.cert
# Private key location (auto generated if the file does not exist)
org.neo4j.server.webserver.https.key.location=ssl/snakeoil.key
Note that the key should be unencrypted. Make sure you set correct permissions on the private key, so that only the Neo4j server user can read/write it.
Neo4j also supports chained SSL certificates. This requires to have all certificates in PEM format combined in one file and the private key needs to be in DER format.
You can set what port the HTTPS connector should bind to in the same configuration file, as well as turn HTTPS off:
# Turn https-support on/off
org.neo4j.server.webserver.https.enabled=true
# https port (for all data, administrative, and UI access)
org.neo4j.server.webserver.https.port=443

About your second question: which channel does the Neo4j Shell's communication use, http or https? The default channel is http.

I locally installed Elasticsearch with X-Pack and Kibana 8.2.2 and made it up and running. I also created a new project with Spring and Java that would connect with Elasticsearch. When running Elasticsearch for the first time it creates a certificate for the http and transport layers.
I want to use a certificate in Spring to login into Elasticsearch. Therefore I added elasticsearch-rest-client. My problem is, which certificate do I need from Elasticsearch to connect to it and be able to create e.g. role-mappings? So that I have superuser rights?
Quoting the documentation:
When Elasticsearch is configured to require client TLS authentication, for example when a PKI realm is configured, the client needs to provide a client certificate during the TLS handshake in order to authenticate. The following is an example of setting up the client for TLS authentication with a certificate and a private key that are stored in a PKCS#12 keystore.
If the client certificate and key are not available in a keystore but rather as PEM encoded files, you cannot use them directly to build an SSLContext. You must rely on external libraries to parse the PEM key into a PrivateKey instance. Alternatively, you can use external tools to build a keystore from your PEM files, as shown in the following example:
openssl pkcs12 -export -in client.crt -inkey private_key.pem -name "client" -out client.p12
How to set up PKI user authentication has a multi-page documentation and you'll be best served by using the one for your specific Elasticsearch version. The current version is available at https://www.elastic.co/guide/en/elasticsearch/reference/current/pki-realm.html but replace the current in the URL with whatever minor version you want to use (like 8.6).
PS: PKI authentication is a platinum licensed feature. But you can of course set it up with the free 30 day trial to see how it works.
I am working in Ec2 instance. I have connected my php files like http://13.57.220.172/phpinsert.php. But it is not secured site. So i want to convert http into https://13.57.220.172.
I have cloudflare ssl. When i try to add ssl certificate. It shows
com.amazonaws.pki.acm.exceptions.external.ValidationException: Provided certificate is not a valid self signed. Please provide either a valid self-signed certificate or certificate chain. Choose Previous button below and fix it.
i have enclose the image with it.
So how can i get the self signed certificate. is there any online tool available.
I think the error message your seeing has to do with this sentence:
If your certificate is signed by a CA, you must include the
certificate chain when you import your certificate.
from https://docs.aws.amazon.com/acm/latest/userguide/import-certificate-prerequisites.html.
Since it sounds like you're not yet in "production" mode, I'm guessing you're not particularly attached to your existing certificate, but just want a certificate to be able to do HTTPS on your web server (and don't really care if it's self-signed).
If you want to use AWS Certificate Manager, I think it would be easier to just let them (AWS) issue you a certificate instead of trying to import one from somewhere else. AWS doesn't charge anything for certificates. https://docs.aws.amazon.com/acm/latest/userguide/acm-billing.html
Even if you get the certificate setup in AWS Certificate Manager, that's not going to be installed directly on your EC2 instance, but rather (most likely) on a load balancer in front of your web server, which will add a little complexity to your setup. https://docs.aws.amazon.com/acm/latest/userguide/acm-services.html
If all you want to do is use HTTPS on your web server, Let's Encrypt (also free) is probably a simpler option. If you are using AWS Linux 2, there are instructions for getting a certificate here - https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/SSL-on-amazon-linux-2.html
Well, add to the points which #jefftrotman has already mentioned.
If your expectation is to just secure your IP address using HTTPS you can achieve that using the below approaches:
A SELF SIGNED certificate that you can create using OpenSSL.
You can also get an SSL certificate from a trust signing authority like (GoDaddy or VeriSign) or Let's encrypt.
The only requirement in the second point is that for getting a certificate from a valid signing authority you need to have a domain name like "myphpapp.com" and then use this domain to get the SSL certificate.
The below details are in case you want to use AWS ACM(Amazon Certificate Manager)
If you prefer ACM, you can get the free Public SSL certificate which you can map to the IP address and your web application will be secured.
If your requirement is to add SSL certificates (like PEM files) to a web server like
NGINX or Apache then you first need to create a Private CA using in ACM and then you using this CA you will be able to create Private SSL certificates. After creating those you can export the files and add those files to the configuration file. (try to use Amazon Linux 2) ec2 image for ease.
I am using HDF 3.0
I create keystore and truststore certificate with path and mention in Nifi ranger policy. While I test the connection I got an issue that I have shown below. I follow this link here
NiFi is secured using TLS certificates. When installed and secured via Ambari, by default Ambari installs a NiFi Certificate Authority (CA) and will generate certificates for each NiFi node and get those certificates signed by that CA.
The NiFI node private key is loaded in the keystore.jks file of each NiFi Node and the public key for the CA is loaded in the truststore.jks file on each NiFi node.
When a client (Ranger in the above case is the client) initiates a connection to NiFi, a two-way TLS connection is negotiated. This involves the server sending the node's public key (derived from the certificate in the keystore.jks) to the client. The client will check that key against a list of trustedCertEntries in its truststore.jks file. If it finds the servers public key or the public key of the CA who signed that server key in the truststore.jks, it will trusted the cert provided by the server. The client will then provide its client certificate (derived from ranger keystore.jks private key) to the target NiFi node. NiFi will follow the same steps above to determine if it should trusted the cert provided from that client using its truststore.jks file.
The error you are seeing indicates that this two-way TLS negotiating is failing because Ranger does not trust the cert being presented by NiFi. If you get past this, you will like have failure of trust the other way as well. You need to make sure the truststore.jks used by both NiFi's nodes and Ranger contains all the necessary "trustedCertEntries" for both sides of this connection. (This means having the public key of the NiFi CA loaded in Ranger's truststore.jks file and loading the public key for your Ranger certificate in the truststore.jks file used by your NiFi instances.
Assume, I have two choices.
Use self-signed x.509 certificate on both the server and client and validate server using its certificate stored in client and authenticate client using client certificate stored in server.
Create only keys on both the server and client and validate server using server key stored in the client and authenticate client using client key stored in the server.
Assume we will use RSA with key length of 2048.
My query is what will be the performance difference. My worry is overhead involved in taking key out of certificate and doing channel encryption.
Our case is there will more number of requests and not much data to flow.
Let me know if you have any queries or concerns.
SSL and SSH they are all have the same functionality, which is Encryption. Both are Cryptographic Network protocols.
SSL:
port: 443
Application : Encryption between browser and server
SSH :
port : 22
Application : Between two Computers
This is the picture of Version Control system which has got SSH key to communicate between user and their repository!

When an application optionally allows you to specify a certificate which represents a certificate authority, what is that doing?
Does that basically set that cert as a "trusted" certificate?
Specific example:
Kibana communicates with elasticsearch. When you configure kibana, you can set the following configuration value:
elasticsearch.ssl.ca
The documentation says this value is an "Optional setting that enables you to specify a path to the PEM file for the certificate authority for your Elasticsearch instance." (source)
Within that same config you're also specifying a certificate and key that can be used for communication with the elasticsearch instance.
If the setting is optional it means that the default behaviour is to use the system Root CAs to validate the SSL Server certificate used by your Elasticsearch instance. If you used a standard commercial SSL Server certificate this should be enough.
Yes, you are setting that certificate as a Root CA but only for this application.
Using the setting you can specify the Root CA used to generated the SSL Server certificate. This is useful if you:
use a selfsigned certificate
use a Root CA that is not available in the system Root CA repository
need to have stringent security settings limiting subset of Root CAs trusted by your application.
