Are you asking the algorithm for un-encryption. Then there is no point of encryption, if you can break it.

anybody know to decode this text:
"bHjlaksplrbfdjQC"
this text was created with ENCODE(".................").
I know it...

Sascha,
I am thinking of a number, iNum, between -999999 and 999999.
iNum MODULO 11 returns 3, and will always return 3.
Can you tell me what iNum is? No!
I suspect that Progress ENCODE will do something similar, but far more complicated than the above example.
If you want to Decrypt, you'll probably have to write your own Encrypt.
Unless, of course, someone knows differently...

Of course, if you had a lot of time to spare you could write some code to generate every possible string of an appropriate length to encode to "bHjlaksplrbfdjQC" and use the encode on those strings. Comparing the output of the encode with the expected result would then tell you the appropriate input string. Just hope you are patient if you try this, it will take quite some time!

You don't know how long the original string was. ENCODE always returns a 16 character long string of upper and lower case letters.
There are 52 to the power of 16 possible combinations, but an infinite (as near as dammit) number of original strings. Just because one matches doesn't mean it's the original.
In my example above, 14 MODULO 11 is 3, but iNum is not 14. If, however, all you want is a value to match the test result, 14 would be fine.
