Question Encode?

[Carlo H. Francisco]

Hi guys, Is there a function, method or syntax for reencode?

I got this sample syntax.

Message encode('caloy') view-as alert-box.

But what about searching the result for that encoded string..hmmmm vice versa i mean..

Any replay is so much appreciated

You want to decode the result? No there isn't something that does that. I believe it's not that difficult to reverse engineer, but the point is you're not supposed to.

There is no DECODE function in Progress. What is encoded stays encoded.
I use this workaround to get the encoded value. I have encoded passwords stored in a table. I use a small brute-force logic and compare the ENCODE(value) to what is stored in the table and get the match. Sometimes when I know a set of possible passwords, I just try to compare ENCODE(value) with what is in the table and identify the password. That worked for me.

you can also make use of ENCRYPT and DECRYPT function.

define variable mykey as raw no-undo.
define variable enc-value as raw no-undo.
define variable dec-value as raw no-undo.

mykey = generate-random-key.

enc-value = encrypt("1234",mykey) .


message encrypt("1234",mykey) decrypt(enc-value,mykey) view-as alert-box.

ENCODE is a hash function. By nature these functions are "one way". Multiple source values can encode to the same result. That's why you cannot reverse it. The approach above using a db table gives you one possible source value. But it is not necessarily *the* source value.
