python - python中的AES-GCM解密

Question

我正在尝试解密从 AES_GCM 生成的密文。密文是从 golang 中的“crypto/aes”库生成的。现在，我正在尝试使用 cryptodome 库破译 python 中的加密文本。

func AESEncryption(key []byte, plaintext []byte)([]byte, error){
   c, err := aes.NewCipher(key)
   if err != nil {
      log.Printf("Error ocurred in generating AES key %s", err)
      return nil,  err
   }

   gcm, err := cipher.NewGCM(c)
   if err != nil {
      return nil,  err
   }

  nonce := make([]byte, gcm.NonceSize())
  if _, err = io.ReadFull(rand.Reader, nonce); err != nil {
    log.Printf("Error ocurred in generating AES key %s", err)
      return nil, err
  }

  return gcm.Seal(nonce, nonce, plaintext, nil), nil

}

plainText := "我会成为我应得的，有没有像自由意志这样的东西？"

python解密代码。

cipher = AES.new(binascii.unhexlify(key), AES.MODE_GCM)
cipher.nonce = binascii.unhexlify(nonce)
cipher.decrypt(binascii.unhexlify(hex_encoded_encrypted_hex))

Answer 1

对我来说就像一个魅力。

from Crypto.Cipher import AES
import binascii

key = binascii.unhexlify('e629ed98829a893899ddda67f582ede72e2a187dd1ddd5ada54f49cfe2c8675f')
data = binascii.unhexlify('9012a33bfb0a51dec4f96404cdd7300ec6afca1fa0d6679a7c036652d014a38faf909e9c44d08dffac121aa85d48b7256fa74542e2545e27dc070adfc03af26f2a32f50c2c311d5c91ff6de2ca3b4347da70669575c9b198f4')
nonce, tag = data[:12], data[-16:]
cipher = AES.new(key, AES.MODE_GCM, nonce)
cipher.decrypt_and_verify(data[12:-16], tag)
