OpenJPA provides an interface for a provider to implement
connection password encryption. Whenever a connection password
is needed, the decrypt(String) method will be invoked. See
org.apache.openjpa.lib.encryption.EncryptionProvider
for the detailed Javadoc.
Notes:
It is an OpenJPA user responsibility to implement the
EncryptionProvider
interface. There is no default implementation.
The interface has an encrypt(String) method,
but it is not called by the OpenJPA runtime.
