OpenSSL Issue

[AWanderingEngineer]

Hi,

First I want to say I'm pretty new at linux and so I apologize in advance is this is a minor issue with an obvious solution. I'm trying to get this package installed and upon running npm install from the node-opcua-logger directory I get several errors having to do with the creation of private keys and certificates using openSSL. I've attached a text file with all the errors (there were several, all related to openSSL). However they all appear to be duplicates of this:

###########OPENSSL ERROR ############
CWD = /home/bmcadmin/node-opcua-logger/node_modules/node-opcua-client

Thanks for any help resolving this issue!

Hi, can you specify some details about your environment?

• OS?
• Node version
• Is openssl installed correctly? Which version?

I have the same issues, both unexperienced and "Can't load /home....../random.rnd into RNG":
My versions are:

user@computer:~/node-opcua-logger$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.2 LTS
Release: 18.04
Codename: bionic
user@computer:~/node-opcua-logger$ openssl version
OpenSSL 1.1.1 11 Sep 2018
user@computer:~/node-opcua-logger$ node --version
v8.10.0

I don't know how to tell if openssl is correctly installed...

As far as I can understand I miss these files:
/node-opcua-logger/node_modules/node-opcua-client/certificates/PKI/own/private/random.rnd
and
/node-opcua-logger/node_modules/node-opcua-server/certificates/PKI/own/private/random.rnd
and
/node-opcua-logger/node_modules/node-opcua-server-discovery/certificates/PKI/own/private/random.rnd

Thanks!

Resolved by doing this...
sudo openssl genrsa -out "/home/user/node-opcua-logger/node_modules/node-opcua-server-discovery/certificates/PKI/own/private/private_key.pem" 2048
sudo openssl genrsa -out "/home/user/node-opcua-logger/node_modules/node-opcua-server/certificates/PKI/own/private/private_key.pem" 2048
sudo openssl genrsa -out "/home/user/node-opcua-logger/node_modules/node-opcua-client/certificates/PKI/own/private/private_key.pem" 2048
cd /home/user/node-opcua-logger/node_modules/node-opcua-client
node test_helpers/create_certificates.js certificate -s -o certificates/client_selfsigned_cert_1024.pem
cd ../node-opcua-server
node test_helpers/create_certificates.js certificate -s -o certificates/server_selfsigned_cert_2048.pem
cd ../node-opcua-server-discovery/
node test_helpers/create_certificates.js certificate -s -o certificates/server_selfsigned_cert_2048.pem

not sure if the sudo bit on openssl commands is really necessary...

Hi @AWanderingEngineer,

certificate generation is done by the underlying node OPCUA library, and I've had problems with it before. Could you try this with the new version (v2) of the logger, which also contains a much more recent version of the node-OPCUA library? Even better, if you download a binary from the release page, you don't need to generate anything yourself.
