If the encryption facilities were built in, or open source plug-in libraries were used, it would be feasible for users to build their own versions of the server or plug- in indeed, there are decompilers available to assist with this process.

defined in separate modules. Firebird ships with two UDF libraries: ib_udf (a widely used “InterBase library”) and fbudf. You can add more libraries, e.g. by buying or downloading them, or by writing them Testing for NULL — if it matters, elsewhere in this guide). The declarations for the shipped UDF libraries can be found in the Firebird subdirectory examples (v.1.0) or UDF (v.1.5 and up). Look at the files

(UDFs) are programs written in an external programming language and stored in dynamically loaded libraries. Once declared to a database, they become available in dynamic and procedural statements as though user-defined BLOB subtypes. External functions for converting BLOB types are stored in dynamic libraries and loaded when necessary. For more details on BLOB subtypes, see Binary Data Types. 5.10.1. server. The UDFAccess parameter in firebird.conf allows editing of access restrictions to filter libraries. Any user connected to the database can declare a BLOB filter. Examples of FILTER 1. Creating
