-------------------------------------------
Summary: SSHD client authentication fails with JDK 1.8.0_161
Key: KARAF-5590
URL: https://issues.apache.org/jira/browse/KARAF-5590
Project: Karaf
Issue Type: Bug
Components: karaf-shell
Reporter: Jean-Baptiste Onofré
Assignee: Jean-Baptiste Onofré
Fix For: 4.0.11, 4.2.0, 4.1.5
After upgrading to JDK 1.8.0_161, the {{bin/client}} fails to connect with:
{code}
"java.security.InvalidKeyException: The security strength of SHA-1 digest
algorithm is not sufficient for this key size"
{code}
It's related to oracle changed the defaults for DSA keys in jarsigner and
keytool in jdk 1.8.151, see
http://www.oracle.com/technetwork/java/javase/8u151-relnotes-3850493.html
I think we can workaround by providing a key to {{bin/client}} and overriding
the one in {{etc/org.apache.karaf.shell.cfg}} configuration file.
At least, it has to be tested.
