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 a C# implementation of the algorithm behind the Progress ENCODE
function specifically to allow this kind of operability.
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.
