Marshalling PKCS8 Private Key in Go
Can PKCS8 private keys be marshaled in Go 1.5? Specifically, is there a method akin to x509.MarshalPKCS1PrivateKey for PKCS8?
Solution:
Despite the absence of a standard function for this task, a custom solution is available:
<code class="go">import (
"crypto/rsa"
"crypto/asn1"
"crypto/x509"
)
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)
}</code>The above is the detailed content of How to Marshal PKCS8 Private Keys in Go 1.5?. For more information, please follow other related articles on the PHP Chinese website!
