The default format is an old SSLeay traditional format which is unique to it. If you can its would be easier to convert to another more standard form such as PKCS#8 or PKCS#12. If you have to use the old format then it is documented in the pem manual page and elsewhere, see: http://www.openssl.org/docs/crypto/pem.html#PEM_ENCRYPTION_FORMAT BTW a 256 bit RSA key will have very little security if that's the command you are using.
