You can either write a short program which places the components into an RSA structure and writes to a file or use the OpenSSL 0.9.8-dev mini ASN1 compiler. In the latter case there's an example in the manual pages for ASN1_generate_nconf() which can be called from the 0.9.8-dev asn1parse utility. Steve. -- Dr Stephen N. Henson.
