Progress OpenEdge 4GL has a function named ENCODE. This function is a one way
hash function that is used by many legacy applications written in Progress to
e.g. hash passwords.
Progress has stated (http://knowledgebase.progress.com/articles/Article/P111508)
that they are not willing to make the algorithm behind the ENCODE function
public. This can cause problems when you need to interoperate with legacy applications.
This project contains implementations of the algorithm behind the Progress ENCODE
function specifically to allow this kind of operability.
If you have a version of this algorithm in a different language, feel free to create a pull request to have it added to this repository. Note however that addition of your code to this repository requires it to conform to the CC0 license.
The unit tests which are part of the project contain a randomly generated set
of inputs and outputs encoded by Progress. The only known issue is that Progress
does not allow NUL characters in strings, so I could not test this. The
list of encoded strings in the unit tests all pass.
Bugs should be reported through github at http://github.com/pvginkel/ProgressEncode/issues.
