Is there a way to marshal a PKCS8 private key in go 1.5?
e.g. something similar to or starting from x509.MarshalPKCS1PrivateKey?

Funny enough, there are no standard function to do that, but here is a custom solution:
type pkcs8Key struct { Version int PrivateKeyAlgorithm []asn1.ObjectIdentifier PrivateKey []byte } func rsa2pkcs8(key *rsa.PrivateKey) ([]byte, error) { var pkey pkcs8Key pkey.Version = 0 pkey.PrivateKeyAlgorithm = make([]asn1.ObjectIdentifier, 1) pkey.PrivateKeyAlgorithm[0] = asn1.ObjectIdentifier{1, 2, 840, 113549, 1, 1, 1} pkey.PrivateKey = x509.MarshalPKCS1PrivateKey(key) return asn1.Marshal(pkey) }
