Hi Bruce,

Thanks for your support, below my answer


1. Are you using binary when FTPing the file?
No but in any case the issue is present also when i decrypt the text "HELLO BY ME" and compare it

2. How are you opening the file?
3. What is the CCSID of the system providing the decryption key?
It's a unix system
4. When you say you "convert string from ebcdic to ascii" are you referring
to the decryption key?
No to the text "HELLO BY ME"
5. How do you detect that the decryption failed? Using debug of the text or
by examining an output file?

Debug and compare the value with the result of

Curious to see suggestions on this one.
I have nothing, sorry.

But just curious why the data wasn’t sftp’d to you instead? But I’m sure
I just don’t see the whole picture of what you are working on.

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
