$ openssl genrsa -out rsa-openssl.pem 3072 $ openssl pkcs8 -nocrypt -in rsa-openssl.pem -inform PEM -topk8 -outform DER -out rsa-openssl.der Folks like Jakob or David likely have a one liner. My notes are kind of old, and this always worked for me. Here's the syntax for X.509 in case you need it: $ openssl genrsa -out rsa-openssl.pem 3072 $ openssl rsa -in rsa-openssl.pem -pubout -outform DER -out rsa-openssl.der Jeff ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [email protected] Automated List Manager [email protected]
