Hi all,
while playing with some ssl setups i stumbled upon the following behaviour that
seems like bug to me ?
As long as all keyentries in a keystore have the same password all is fine.
Using entries with different password tomcat doesnt startup.
For testing:
At first create 2 different keystores (same.jks and different.jks) having each
2 entries:
# create 2 entries with same keypass for each entry
keytool -genkeypair -alias tomcat1 -storepass storepass -keystore same.jks
-keyalg RSA -keypass keypass -ext san=dns:tomcat1 -dname CN=tomcat1
keytool -genkeypair -alias tomcat2 -storepass storepass -keystore same.jks
-keyalg RSA -keypass keypass -ext san=dns:tomcat2 -dname CN=tomcat2
# create 2 entries with different keypass for each entry
keytool -genkeypair -alias tomcat1 -storepass storepass -keystore
different.jks -keyalg RSA -keypass tomcat1 -ext san=dns:tomcat1 -dname
CN=tomcat1
keytool -genkeypair -alias tomcat2 -storepass storepass -keystore
different.jks -keyalg RSA -keypass tomcat2 -ext san=dns:tomcat2 -dname
CN=tomcat2
setup a SSL Connector to use that keystore:
<Connector
port="443"
URIEncoding="UTF-8"
scheme="https"
secure="true"
SSLEnabled="true"
>
<SSLHostConfig
ciphers="HIGH:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!kRSA"
protocols="all">
<!-- doesn't work, use keypass for alias tomcat2 -->
<Certificate
certificateKeystoreFile="different.jks"
certificateKeystorePassword="storepass"
certificateKeyAlias="tomcat2"
certificateKeystoreType="JKS"
certificateKeyPassword="tomcat2"
type="RSA"
/>
<!-- working config -->
<!--
<Certificate
certificateKeystoreFile="same.jks"
certificateKeystorePassword="storepass"
certificateKeyAlias="tomcat2"
certificateKeystoreType="JKS"
certificateKeyPassword="keypass"
type="RSA"
/>
-->
</SSLHostConfig>
using the config snippet tomcat fails on startup with the following excpetion:
java.lang.IllegalArgumentException: java.security.UnrecoverableKeyException:
