我現在真的很難在我的代碼中找到錯誤——任務是將一個字符串加密到一個 pgp ASCII 裝甲文件中——這是一件簡單的事情。受此要點啟發，我使用以下函數：// pgp encryption using the pgp RSA certificate// massive thx to https://gist.github.com/jyap808/8250124func encToFile(secretString string, filename string) (string, error) {  log.Println("Public Keyring: ", publicKeyring)  encryptionType := "PGP MESSAGE"  // Read in public key  keyringFileBuffer, _ := os.Open(publicKeyring)  defer keyringFileBuffer.Close()   entityList, err := openpgp.ReadArmoredKeyRing(keyringFileBuffer)   check(err)  encbuf := bytes.NewBuffer(nil)  w, err := armor.Encode(encbuf, encryptionType, nil) // the encoder somehow makes this into ASCII armor  check(err)  plaintext, err := openpgp.Encrypt(w, entityList, nil, nil, nil)  check(err)  message := []byte(secretString)  _, err = plaintext.Write(message)  plaintext.Close()  w.Close()  // Output encrypted/encoded string  log.Println("Writing Encrypted Secred to: ", filename)  // we write the file into a file  err = ioutil.WriteFile(filename, encbuf.Bytes(), 0644)  check(err)  log.Println("File:\n", encbuf.String())  return encbuf.String(), nil}但是，另一端的人收到此錯誤消息：gpg: encrypted with RSA key, ID 5BE299DCgpg: decryption failed: No secret key非常歡迎提示和建議！
