org.apache.fulcrum.yaafi.framework.crypto.CryptoStreamFactory

extends Object

Factory class to get a decrypting input stream for reading configuration files. The implementation uses dynamic class loading to make decryption an optional feature which is highly desirable when avoiding the ECCN export code problems.
