Release 10.1A: OpenEdge Deployment:
Managing 4GL Applications

Possible drawbacks of encrypted source

Encrypted source code has a number of possible drawbacks:

Does not prevent index modifications — When compared to r-code, encrypted source is less restrictive because it allows modifications to the database’s indexes. Whether this is an advantage or disadvantage depends on whether you want to give the user the flexibility to change indexes. If your code explicitly specifies indexes in its search criteria, user modifications to your indexes might invalidate your code.
The Encrypted Compiler Mode (-rx) parameter changes the capabilities of the Compiler — When you start OpenEdge with the -rx parameter, the Progress Compiler can compile only encrypted source, not unencrypted source. If users have the 4GL Development System, OpenEdge Studio, OpenEdge Architect, or WebSpeed Workshop, they must start OpenEdge again without the -rx parameter to write and compile their own procedures.
