data-help-name="OpcUa-Endpoint2"> # notes: ## Where is the PKI ? - `@opcua/for-node-red` stores its PKI in the following folder | Platform | Location | | -------- | ------------------------------------------------- | | Linux | "~/.config/opcua-for-node-red-nodejs/PKI" | | Windows | %APP_DATA%\Roaming\opcua-for-node-red-nodejs\PKI" | - This PKI is shared by all endpoint connection nodes in order to avoid having to generate multiple certificates for each endpoint and facilitate the management of the certificates. - all OPCUA Client connection that are created by the OPCUA Endpoint node will use this PKI. #### PKI folder structure ```console └─ 📂 certificates └─📂 PKI ├─📂 issuers │ ├─📂 certs │ └─📂 crl ├─📂 own │ ├─📂 certs │ │ └─🔐 client_certificate.pem │ └─📂 private │ └─🔐 private_key.pem ├─📂 rejected └─📂 trusted ├─📂 certs └─📂 crl ``` ## Secure connections: When using a secure connection to the OPCUA server, you'll have to make sure that the server certificate is trusted by the client and that the client certificate is trusted by the server. This is needed to ensure that the connection is secure and that the data is not intercepted by a third party. Client and Server uses public key stored in certificates of the other party and its own private key to encrypt and decrypt data. If the `@opcua/for-node-red` client certificate is not trusted by the server, the server will refuse the connection. connection to endpoint opc.tcp://machine:4840 could not be established ### ensuring that the `@opcua/for-node-red` client certificate is trusted by the server - If you are using a "Sign" or "SignAndEncrypt" connection to the OPCUA Server, you'll have to make sure that your client certificate is trusted by the server. - This can be done by copying the client certificate of your `@opcua/for-node-red` instance to the server and adding it to the trusted certificates folder in the PKI of the server. - (you can download the client certificate in PEM or DER format from the OPCUA Endpoint node, using the provided buttons) - The client certificate can be found in the "pki" folder of the OPCUA Endpoint node. - The certificate is named `client_certificate.pem` and is located in the PKI folder (see above) at this location `PKI/own/certs/` - Refers to your server documentation to know where to copy the client certificate. ### ensuring that `@opcua/for-node-red` trusts the server certificate - Similarly, if you are using a "Sign" or "SignAndEncrypt" connection to the OPCUA Server, you'll have to make sure that the server certificate is trusted by the client. - By default, `@opcua/for-node-red` is setup to automatically accept any server certificate. This can be changed by setting the "rejectUnauthorized" option to true the global settings of the OPCUA Endpoint node. ( available to Pro version only) ## default certificate generation - A default self-signed certificate generation is done by the `@opcua/for-node-red` node when it is first deployed. - The certificate is generated in the "pki" folder of the OPCUA Endpoint node. - The certificate is named "client_certificate.pem" and is located in the folder ## How to provided my own key pair (client certificate and private key) ? - You can provide your own key pair by copying the client certificate and private key in the "pki" folder of the OPCUA Endpoint node. - The certificate must be named "client_certificate.pem" and stored in the "pki/own/certs" folder. - The private key must be named "private_key.pem" and stored in the "pki/own/private" folder. - If your certificate is not a self-signed certificate, you'll have to also copy the certificate of the Certificate Authority that signed your certificate in the "pki/issuers/certs" folder and its CRL (Certificate revocation list) in the "pki/issuers/crl" folder. </script> //# sourceMappingURL=OpcUa-Endpoint2.html.map
