I then send PGP RSA encrypted data offsite.  Am I not offloading processing to 
crypto hardware (CEX2) during encryption?

PGP encryption does not use the hardware (CPACF/ CEX2). The data is encrypted 
with PGP

RSA encryption does use CEX2 crypto hardware in Accelerator mode (CEX2A) . The 
PGP encryption keys are encrypted with RSA

Subject: OpenPGP doesn't use crypto hardware? was Re: OpenPGP Encryption

Re: "PGP is good encryption but it is not in use very much on IBM mainframes 
because the encryption can not be offloaded to crypto hardware ..."

I'm confused since the OpenPGP doc mentions hardware encryption in several 
places.

I recently had a project to get OpenPGP working on z/os 1.13.  I am using a 
public/private key pair generated with ICSF in the PKDS.  We have 2 CEX2 cards. 
 I '-prepared' my key pair with OpenPGP. During encryption I specify '-provider 
com.ibm.crypto.hdwrCCA.provider.IBMJCECCA.' I then send PGP RSA encrypted data 
offsite. 

Am I not offloading processing to crypto hardware (CEX2) during encryption?
