processing openssl-encrypted files through pgdump and pgrestore

Good afternoon,

We run postgres 9.2.12
We've been given a mandate to encrypt all our database backups.
We also use the -f Fc subcommand in pgdump to create pg_restore suitable
input/output files

The first step to create the encrypted dump works fine:
*pg_dump -U postgres auth_production_test -Fc | openssl enc -aes-256-cbc
-kfile /home/postgres/.openssl.postgres.pass -e >
/storage/backups/dbdumps/authproductiontest.custom.gz.enc &*

However when I run pg_restore with the -l option to create the table of
contents, pg_restore doesn't recognize the encrypted backup as a suitable
archive:

*pg_restore -l -U postgres authproductiontest.custom.gz.enc >
authproductiontest.list | openssl enc -aes-256-cbc -kfile
/home/postgres/.openssl.postgres.pass -e >
/storage/backups/dbdumps/authproductiontest.custom.list.enc &*
*[2] 1070*
*[postgres(at)diablo dbdumps]$ pg_restore: [archiver] input file does not
appear to be a valid archive*

Do I need to create an unencrypted dump first for pg_restore to recognize
and act upon? I don't see anything in the pg_restore documentation that
allows for reading encrypted files.

Any suggestions welcome. Thanks,
