I work on the TPM stack and have to convert TPM structures to RSA public key structures for ooenssl to utilize, and we use this routine along the way. I would imagine theirs a higher level public from private routine you can call. I would dissect what: openssl rsa -in mykey.pem -pubout > mykey.pub Is doing > > any help with SPKI welcome! > J >
