Utility to Import external RSA pem key into TPM

Duplicate tool - Takes RSA private key in
pem format as input and generates
TPM structured buffers as expected by tpm Import

Import tool - Takes input buffers from
Duplicate tool and results in pub/priv blobs
which can be used to load the key in tpm
storage heirarchy's as child to primary key
