Java cryptographic strength policy
Due to local laws and export restrictions the containers use Java with a limited cryptographic strength policy. Some openHAB functionality may depend on unlimited strength which can be enabled by configuring the environment variable CRYPTO_POLICY=unlimited
Before enabling this make sure this is allowed by local laws and you agree with the applicable license and terms (see OpenJDK (Cryptographic Cautions)).
The following functionality depends on the unlimited cryptographic strength policy:
- KM200 Binding
- Linky Binding
- Loxone Binding
- MQTT Binding
- openHAB Marketplace
