Re: Encryption methods on the i

If I wanted to use a digital certificate for the encryption / decryption
keys, what would be needed on the i and what would be needed on the windows
system. I am thinking of using PKZIP for the encryption / decryption.

Brad,
This is a requirement from the client.
They want to encrypt the file on their side before transmission to prevent
unauthorized access to the data.
I do not know what type of system they are using or what method they use
to place the files on the IFS.

I have requested this information from the client and am waiting for a
response.

Is there a reason that you can't just use SSL or TLS for the transmission
(either over FTP or HTTP)?

Of course, making sure your OpenSSL is patched first. :)

Why add a layer of complexity on both ends when you can have the system do
it for you?

The API's David pointed out are what you want.

Realize that you'll need to open the file in binary mode and the the
decrypted results will be in ASCII.

They are sending ascii csv data, so the records and fields with them
are
varying length.

Encrypting the actual data, or the communication?
For example, I could use sftp to transfer files encrypted between
two
systems. That would encrypt the communications but not the actual
data
itself. You could put a sniffer on that comm but you would not be
able
to
make any sense out of that.
Many people use free sftp between disparate entities.

Subject: Encryption methods on the i
Sent by: midrange-l-bounces@xxxxxxxxxxxx



All,
I have a client that is presently sending files from another system
(not
i)
to the IFS in CSV format..
They are planning to encrypt the data prior to transmission and my
program
will need to decrypt it before processing.

What encryption / decryption methods are available on the i to do
this?
At this time, the client has not chosen an encryption method and
they
want
to ensure that the decryption process is available for the i.

At this time, they are not looking for a commercial solution, and I
would
prefer a solution that could be used an ILE RPG program, or a system
command.

TIA,
