Hello,

Currently in prconfig.xml we have these password hardcoded for the stream.
<env name="services/stream/encryption/security/protocol" value="SSL"/>
  <env name="services/stream/encryption/truststore/path" value="/opt/pega/certs/pega-cs.p12"/>
  <env name="services/stream/encryption/truststore/password" value="XXX"/>
  <env name="services/stream/encryption/keystore/path" value="/opt/pega/certs/pega-cs.p12"/>
  <env name="services/stream/encryption/keystore/password" value="XXX"/>

Now, for security reason, we wanted to dynamically change password value. we have tried with environment variable, but it's not able to read. 

<env name="services/stream/encryption/security/protocol" value="SSL"/>
  <env name="services/stream/encryption/truststore/path" value="/opt/pega/certs/pega-cs.p12"/>
  <env name="services/stream/encryption/truststore/password" value="{KEYSTORE_PASSWORD}"/>
  <env name="services/stream/encryption/keystore/path" value="/opt/pega/certs/pega-cs.p12"/>
  <env name="services/stream/encryption/keystore/password" value="{KEYSTORE_PASSWORD}"/>

can you please advise how we can dynamically change the password value?
