java - The publicKey should not be null when trying to PGP encrypt in Mule -

i'm trying pgp encrypt message using mule, i'm getting "publickey should not null" error.

i replaced local_policy.jar , us_export_policy.jar here: c:\program files\java\jdk1.7.0_45\jre\lib\security

in library have: bcpg-jdk15on-150.jar. added local_policy.jar (not sure need tried , without , got same error).

i'm running mulestudio 3.5 , ce-3.4 runtime.

the exception occurs since using muleheadercredentialsaccessor , have not set header mule_user or set value not match uid in keyring.

either have set header (inbound property) or implement own credentialsaccessor returns correct credentials.

you can find code muleheadercredentialsaccessor , on this page there simple example credentialsaccessor returns hard coded credential.
