Never use a small public exponent in RSA keys. The recommended exponent is 65537. The key for this level is weakrsakey.

I have just pasted it to save my time.

One way to do this is to generate a DER encoded key using
 OpenSSL's asn1parse command's -genconf option.

You'll need to construct an input file for 
asn1parse -genconf to produce an RSA key in the standard format (per RFC 3447). 

The syntax for asn1parse -genconf is given here: 
http://www.openssl.org/docs/crypto/ASN1_generate_nconf.html and indeed,
