Folks,

I'm nearly embarrassed having to ask this but I'm having issues starting up the Management Interface in the embedded Tomcat scenario.

The error is technically obvious:

Caused by: java.security.UnrecoverableKeyException: failed to decrypt safe 
contents entry: javax.crypto.BadPaddingException: Given final block not 
properly padded. Such issues can arise if a bad key is used during decryption.


Environment is:

CAS Version: 6.1.0-RC4

Now this isn't my first rodeo ride with certificates so  here is what I've done so far trying to solve this.


* Confirmed the the management.properties file being picked up by the run-time is correct (put in incorrect directive and it complained).

* Confirmed Syntax for the Certificate Directives via examples and the CAS interactive Shell.

management.server.ssl.key-store: file:/Users/colinr/DevTree/devkeystore.jks
management.server.ssl.key-store-password: <password>

It should be noted that the keystore is of type PKCS12 and it's the exact same keystore as being used by my standalone Tomcat 9.0.26 environment that CAS itself runs on successfully. Said tomcat environment is started by the same users that runs the embedded one.

* I've opened up permissions to the file totally.

* I'm able to "keytool -list" the certificate in this keystore directly via "keytool" and responds properly to the correct and incorrect keystore password.

* I'm able to view details of certificate via keytool

* Certificate alias is tomcat

* Certificate is NOT expired.

* Certificate is loaded in the the Java's truststore via the InstallCert tool.

* I tried generating a new keystore via "keytool -genkeypair -alias tomcat -keyalg RSA -keysize 2048 -keystore managementkeystore.jks -validity 3650  -storepass testadmin" same result.

* keytool and activated Java environment for the run time is from the same distribution.

* I've run the overlay before like this without issues, however that was 6.0.2-SNAPSHOT on 10.15.4.


Frankly I'm totally stumped but expect the issue to be an embarrassingly obvious one.

Cheers


Colin
