You could do it all on z/OS, assuming that you have the encryption program
there that you want. Many are available.
For example, using our Co:Z Toolkit it would be something like:
//SHELL EXEC PGM=COZBATCH, # a better BPXBATCH
// PARM='/ IDSN=HLQ.MY.DSN'
//ENCRYPT DD DISP=(NEW,CATALOG,DELETE),SPACE=(..),
// DCB=(RECFM=U,BLKSIZE=27998),
// DSN=...
//STDIN DD *
# first get a checksum hash of the EBCDIC data.
# see the z/OS Unix cksum doc for more information and options
fromdsn -b $IDSN |
cksum > cksum.txt
# convert to ascii using your favorite encoding, preserving trailing record
# spaces, using newline terminators.
# Pipe the output into your encryption program (or directly to a file
# and encrypt in a separate step)
set -o pipecurrent
fromdsn -k -l nl -s IBM-1047 -t ISO8859-1 $IDSN |
my-encrypt-program |
todsn -b //DD:ENCRYPT
