omero-certificates 0.2.0

OMERO server certificate management plugin

OMERO server certificate management plugin

Generate self-signed certificates and configure OMERO.server.

If you prefer to configure OMERO manually see the examples in these documents:

• https://github.com/ome/docker-example-omero-websockets
• https://docs.openmicroscopy.org/omero/5.6.0/sysadmins/client-server-ssl.html

Installation

Install openssl if it's not already on your system. Then activate your OMERO.server virtualenv and run:

pip install omero-certificates

Usage

Set the OMERODIR environment variable to the location of OMERO.server.

Run:

omero certificates

OpenSSL 1.1.1d  10 Sep 2019
Generating RSA private key, 2048 bit long modulus (2 primes)

certificates created: /OMERO/certs/server.key /OMERO/certs/server.pem /OMERO/certs/server.p12

to update your OMERO.server configuration and to generate or update your self-signed certificates. If you already have the necessary configuration settings this plugin will not modify them, so it is safe to always run omero certificates every time you start OMERO.server. You can now start your omero server as normal.

This plugin automatically overrides the defaults for the following properties if they're not explicitly set:

• omero.glacier2.IceSSL.Ciphers=HIGH: the default weaker ciphers may not be supported on some systems
• omero.glacier2.IceSSL.ProtocolVersionMax=TLS1_2: Support TLS 1.1 and 1.2, not just 1.0
• omero.glacier2.IceSSL.Protocols=TLS1_0,TLS1_1,TLS1_2: Support TLS 1.1 and 1.2, not just 1.0

The original values can be found on https://docs.openmicroscopy.org/omero/5.6.0/sysadmins/config.html#glacier2

Certificates will be stored under {omero.data.dir}/certs by default. Set omero.glacier2.IceSSL.DefaultDir to change this.

If you see a warning message such as

Can't load ./.rnd into RNG

it should be safe to ignore.
