Re: Crib Sheet for RSA Key Encryption -- MIDRANGE-L

I will be receiving identification data from a trading partner. They are
receiving the information from a signature capture device located at my
facility. The signature capture device will encrypt the information using
their key (on the device). They will receive the information and decrypt
it. They will then in turn encrypt the data with my private key. I'll then
need to decrypt with my private key and use it for further processing.

The transport mechanism is a socket program that I developed. I'll start
the transaction from the IBMi to the device with a socket send. The device
will then communicate with the trading partner, The trading partner will do
the decrypt/encrypt and return the data to the device. The device will
return the data to my program when I issue a socket recv.

What are you trying to do exactly?

I'm hoping to use the SQL Encrypt and Decrypt functions. Would those work
for encrypting and decrypting file data?

You're missing some fundamental information here. Generating the key pair

is the easy part but what are going to do then? What protocol are you
going
to use to encrypt the data? Public keys aren't an encryption method.

Hey folks...anyone have a crib sheet for encryption? I have a need to

generate a 2048 bit RSA public/private key pair. I'll send the public
key
to a trading partner. They'll encrypt a file and return it to me, where
I'll decrypt it. I'm familiar with public/private keys with SSH type
things, but the IBM documentation about how to generate and use an RSA
key
seems a bit tough to dig through. Hoping someone has blazed this trail.
Thanks!
