RE: Encrypted Data to File

The recent series of cryptographic APIs by Example articles are based on
the key managament APIs introduced with release V5R4. Some time ago I
wrote another series of articles covering this topic and providing the
same functionality, that were based on the APIs available in release
V5R3. You'll find links to these earlier articles at the end of the
article published yesterday, but I've also included them here:

Very nice...looks I have some more reading in store! :)

Question: What can be used in V5R3? Some of the key management utilities
are only available in V5R4 and higher, correct?

Thanks...

Your assumption is correct, Michael. - Here's some more information
on the subject that might help explain the use of a salt in this

As coincidence would have it, this week's programming newsletter also

includes an article covering this topic, together with more code
examples:

The article doesn't appear to be on-line yet, but it should be soon.

Good refs Buck...thanks.

How would this be implemented in the cryptographic APIs? Would this
be used for the Initialization Vector?
