New to cryptography, I'm using IBM callable services CSNBENC and CSNBDEC
to encrypt/decrypt fields in SMS files. It seems I need to obtain a key
identifier by calling CSNBKGN and also specify an initialization vector to
encrypt. Are these two calling parameters 'keys' for the encryption? Are they
stored somewhere (and retreivable for decryption) in the calling services
software? or do I store one or both of them on my own in a file secured by
some means? The IBM manuals seem to assume a level of knowledge I just
don't have on this subject. Help!
The vestor is not stored anywhere. The key can be stored in CKDS
dataset. Of course key value is encrypted using another key (master
key). You can use such a key (this from CKDS) or simply provide your
own, in clear form. The last option is less secure.
