dumpasn1 truncates some stuff over 128 bytes in length. The -a options
stops that.

You don't dream in ASN1. You have nightmares!

DER encoded PKCS#1 RSAPrivateKey structure. If you save each array to a

openssl rsa -in key.der -noout -text

should give something readable. Alternatively call RSA_print() on the
RSA structure.
