What sort of data are you going to encrypt? This might influence the
algorithm you choose to use.

Just text.

Will the PCs be able to access the IBM i machine or will they be
standalone?

The PC won't be able to access the iSeries until the data is decrypted.

Thanks for those ... the info on Mr. Klement's page seem especially useful.

routines won't encrypt the same text in ASCII and EBCDIC the same).
Maybe Unicode?

Use iconv() to convert between EBCDIC and UTF-8:

I knew about iconv ... I'm thinking I will need to convert the data to
Unicode before encryption and back to ebcdic after decryption in order to
get the correct result.
