## Signature Repository

The Signature Repository is where BEA Guardian keeps its locally persisted store of signatures available for evaluation. When you download signatures from the Guardian update site, they arrive in a Java Archive (JAR) file. The JAR file is stored in the repository/archives directory of your Guardian installation directory.
