Data encryption

Dear All,

I need to decrypt some text related data coming from a supplier, i receive the file in an ftp folder read text and decrypt it.

In order to decrypt the information i use Qc3DecryptData (AES OR RC4 alghoritym), unforntunately i encoured in the following problem

First of all let's me say that i was not able to decrypt the data coming from vendor so i try to understand where the problem was

First of all i have written a program that encrypt and decrypt the phrase "HELLO BY ME" with key "key encryption" and it's work fine.

I compare the result with the one coming from the following url

http://rc4.online-domain-tools.com/

and the two values doesn't match.

So my first assumption was that there is a difference beetwen ebcdic and ascii transcodification so i try to

- convert string from ebcdic to ascii

- run encryption

but again the two values doesn't match

Anyone can direct me ? any idea ?


Thanks to All


Basilio
