Expenses Corporate Credit Card PGP encryption key transferability

Hello colleagues,

We are integrating corporate credit card transactions into Fusion Expenses. We are setting up integration between our bank and OIC server. Bank will SFTP the encrypted transactions file to OIC. We will then pull the encrypted file from fusion expenses using 'Upload and Validate Corporate Card Transaction File' process.

Question: Can we generate the PGP Encryption Certificate from Production and reuse the same certificate in TEST? 

(because the Bank will only perform one-time setup with a single certificate).

Thanks.
