Thank you so much.  It works. These example codes and your advice help
me a lot.
Further, I'd like to ask a question about performance.

In these examples,
The two objects are invoked to sign and to verify a message
respectively.
CryptoPP::RSASSA_PKCS1v15_SHA_Signer
CryptoPP::RSASSA_PKCS1v15_SHA_Verifier

I surveyed many RSA OAEP and PKCS specification and related document.
In fact, I studied network security and cryptography theory before.
However, I still can't understand that the signing operation is so far
slower then verifying operation.  I measure them by myself and the
following page shows that the verification is far faster also.

Why are the performances so different?   Thanks again.
