Trf is a TCL extension library. It extends the language at the C-level with so-called ``transformer''-procedures. The package is able to intercept all read/write operations on designated channels, thus giving it the ability to transform the buffer contents as desired. This allows things like transparent encryption, compression, charset recoding, etc. Build upon this framework (and as proof of concept) a collection of tcl-level commands was implemented, most of them related to cryptography.
