I'm trying to generate keypair with openpgp lib and when I want to test it by encrypting a test string, it returns the following error openpgp: invalid argument: cannot encrypt because no candidate hash functions are compiled in. (Wanted RIPEMD160 in this case.). However it works when I pass a public key exported from gpg.
Also I'm wondering how to encrypt the private key like gpg --generate-key does?
func main() {
var e *openpgp.Entity
var pubKey *bytes.Buffer
e, _ = openpgp.NewEntity("testUser", "test", "test@test.test", nil)
for _, id := range e.Identities {
err := id.SelfSignature.SignUserId(id.UserId.Id, e.PrimaryKey, e.PrivateKey, nil)
if err != nil {
fmt.Println(err)
return
}
}
buf := new(bytes.Buffer)
w, err := armor.Encode(buf, openpgp.PublicKeyType, nil)
if err != nil {
fmt.Println(err)
return
}
e.Serialize(w)
w.Close()
pubKey = buf
// Encrypting test with public key
entity, err := openpgp.ReadArmoredKeyRing(pubKey)
if err != nil {
fmt.Println(err)
return
}
buf = new(bytes.Buffer)
encoderWriter, err := armor.Encode(buf, "PGP MESSAGE", make(map[string]string))
if err != nil {
fmt.Println(err)
return
}
encryptorWriter, err := openpgp.Encrypt(encoderWriter, entity, nil, nil, nil)
if err != nil {
fmt.Println(err)
return
}
encryptorWriter.Write([]byte("hello world"))
encryptorWriter.Close()
encoderWriter.Close()
fmt.Println(buf.String())
}
