Re: Encryption for Dummies?



fixed

James - you can USE the SQL functions without storing anything in a PF. Chuck Pence mentioned this already, I believe. Use the SET or VALUES function, I believe.

This seems the easiest way to do stuff here. Scott's example, which I've looked at and played with, uses the RC4 algorithm - it might be fine for your use, it's a stream algorithm - not a block one like AES that is usually preferred. AES is a little more complex to set up - you have to pad out to block length, generate an initialization vector, etc. Service program time.

Of course, the SQL stuff does require a certain minimum release of OS400 - I don't remember what it is, right now.

CIPHER is a great way to go - I'm using it now because I don't have time to work out the validation list APIs. Deadline for a release, is all - I'll probably go with them eventually.

Before V5R4 you have to have product 5722-AC3 installed in order to use RC4 or AES = to use anything beyond the 4 or 5 simple one-way hash-type algorithms available even without AC3.

I don't remember now what your minimum release is - if v5r4, you have lots of stuff to help with encryption, and SQL has a lot of it.

Carsten Flensburg has had several articles that might help. And if you have IBM partner support, they have some nice samples, as well.

there is no practical reason to waste 36k to store (maybe) 32 bytes.
(It's ridiculous enough to waste 8k on storing them in a *DTAARA!) So
how would SQL encryption even apply?
