Security in MATLAB Code

Security considerations for sensitive information and intellectual property in MATLAB® code

You can increase the security of your workflow by keeping sensitive information out of code and by obfuscating code. You can store sensitive information in your MATLAB vault or in a .env file. For more information, see Keep Sensitive Information Out of Code. When obfuscating code, consider combining multiple approaches. For more information, see Security Considerations to Protect Your Source Code.
