cyberphone

Code showing a payment authorization where all data is signed.
Since some of the signed data contains PII this part is removed
(after being signed) and then encrypted using a public key.
The encryption key is issuer-wide for avoiding PII.

The goal is creating a compact container only needing a single
signing and encryption operation.  By keeping the transaction
request in clear, data duplication is minimized.

The need for encryption is because the authorization is sent back
