When MATLAB® Compiler™ or MATLAB Compiler SDK™ creates an application or shared library, it bundles the content into an embedded deployable archive, which is known as the CTF archive. The archive contains all the MATLAB based content (MATLAB files, MEX-files, and so on) included in the application.
All MATLAB files (
.p files) included in the
deployable archive are encrypted using the Advanced Encryption Standard (AES) cryptosystem.
By default, the names of files and the directory structure are not obscured and other file
types, including MEX-files, MAT-files, FIG-files, Java JAR or class files, are not
encrypted. Every other type of file is copied, unchanged, into the archive. When the
deployable application runs, the files in the CTF archive are extracted onto the disk, and
any files that were encrypted in the archive remain encrypted on the disk. If you choose to
extract the deployable archive as a separate file, the files also remain encrypted.
Starting in R2022b, you can obscure the names of files and the directory structure, and
also encrypt other file types (such as MAT, FIG, MEX, and so on) using the
-s option for
mcc. At run time, the encrypted files remain encrypted on
the disk but are decrypted in memory to their original form before compiling. You can use
this option with the
-j option to create P-coded files from MATLAB code files before they are compiled.
For more information on how to extract the deployable archive refer to the references in the following table.

Multiple deployable archives, such as those generated with COM components, .NET assemblies, or Excel add-ins, can coexist in the same user application. You cannot, however, mix and match the MATLAB files they contain. You cannot combine encrypted and compressed MATLAB files from multiple deployable archives into another deployable archive and distribute them.
All the MATLAB files from a given deployable archive associate with a unique cryptographic key. MATLAB files with different keys, placed in the same deployable archive, do not execute. If you want to generate another application with a different mix of MATLAB files, recompile these MATLAB files into a new deployable archive.
The compiler deletes the deployable archive and generated binary
following a failed compilation, but only if these files did not exist
before compilation initiates. Run
help mcc -K for
Release Engineers and Software Configuration Managers: Do not use build procedures or processes that strip shared libraries on deployable archives. If you do, you can possibly strip the deployable archive from the binary, resulting in run-time errors for the driver application.
