Hello Team,

I have developed one script for weld connections.

But before giving to the user, I want to encrypt the script.

So, how to achieve this?

Any help will be great.

    As far as I know there are no longer recommended ways to encrypt tcl files. There were, and are, some ways out there but there were security issues and are therefore not recommended.  Compose, C++ and Python can all be encrypted/compiled.  So if encryption is critical you might try a different language.  A web search for py_compile and compileall will give you more information on Python compiling.

    Thank you for the information @Ben Buchanan and @Quy Nguyen Dai .

    I have developed one shell weld connection script and want to deploy it for user's use.

    So, any information on deployment will be a great help.

    I prefer to use extensions to deploy scripts.  Check out my blog below for more information on extensions.

    @Ben Buchanan As you have mentioned about python.

    Is it possible to do scripting python for Hypermesh macro.

    IS API of python available?

    Unfortunately no. Python API is coming to HM but not released yet.  So as with Compose and C++ you would have to incorporate the tcl HM api commands somehow into your code. Python api is available in other Altair products like inspire (see below)

    1) What about binary *.tbc files? Hypermesh can run tbc files. Do we still have converter? It was part of TclPro, but now.... 

    2) It is possible to use encryption using \hwsolvers\optistruct\bin\win64\os_encrypt_win.exe Read about it in this chapter of help: /help/hwsolvers/os/topics/solvers/os/run_os_encryption_r.htm It could be useful.

    For example, you can hide some materials properties: MAT1 card

    MAT1    120     1.E6          0.0     3.57      1.0e-4          35.E3   35.E3   23.E3

    with 

    /ENCRYPT/ZB001 1GcxRn2nMRIp575cxxQrdIBaZYBB6oPGNhPJh4lAZOH9HdVivEeMVIGEJWJM5T0q6O3zzUH3KyJRJ5OOjx6ojdd9OjHT4C63ko2I %ZB001MGoRMaLooUWUaHxbHHbErfqmYfVVMh9h2TgKcZvYw13940WzdJv0cS2KuK77XBDGBvyMtNikHbfwlaasrGdSkKAZZrEdrP %ZB001gbGGRgQ0GQMCYNi4HIdcbTbCFWcJDnCH7UfhSwwjZTammusHl9juHaAT5pxPeNVdkwv9OqH44OTmv5XeiD1uaSxTNH2u8i %ZB001P0av0XqspIeqUWja5CVLjvismTRhTLOPOmTJyK3FPyeh77evhjFZxmANrKrdXpoML6xTMkK8emlwoN9vYumaBvqRLsg8zs %ZB001H80ZXXnnhZ6cViaSBly3G4xhptIpGKWYjyXThW7R1ERUrmBjxBq7mpKX5hno4LdLitUvMUjOlSFJYy507eyyakjnKtzvU7

    and hypermesh will understand it.

    Hello all,

     

    I have used TCLPro setup to convert .tcl file to .tbc.

    And it's working good in HM 2022.3
