我正在尝试使用 Tink 和 HashiCorp Vault 进行加密和解密。当我尝试使用相同的 AEAD 对象在同一会话中加密和解密时,它工作正常。但是,如果我将先前加密运行的结果存储在文件中,然后尝试仅在此文件上运行解密函数,则会遇到错误,提示“在流中找不到密文的匹配密钥。” p>
我附上了代码供参考:
keyUri := "hcvault://my-vault-url.com/transit/keys/my-key2" vaultClient, err := hcvault.NewClient(keyUri, tlsConfig(), vaultToken()) if err != nil { log.Fatal(err) } kekAEAD, err := vaultClient.GetAEAD(keyUri) if err != nil { log.Fatal(err) } // Generate a new keyset handle for the primitive we want to use. newHandle, err := keyset.NewHandle(streamingaead.AES256GCMHKDF1MBKeyTemplate()) if err != nil { log.Fatal(err) } // Choose some associated data. This is the context in which the keyset will be used. keysetAssociatedData := []byte("keyset encryption example") // Encrypt the keyset with the KEK AEAD and the associated data. buf := new(bytes.Buffer) writer := keyset.NewBinaryWriter(buf) err = newHandle.WriteWithAssociatedData(writer, kekAEAD, keysetAssociatedData) if err != nil { log.Fatal(err) } encryptedKeyset := buf.Bytes() reader := keyset.NewBinaryReader(bytes.NewReader(encryptedKeyset)) handle, err := keyset.ReadWithAssociatedData(reader, kekAEAD, keysetAssociatedData) if err != nil { log.Fatal(err) } streamingAEAD, err := streamingaead.New(handle) if err != nil { log.Fatal(err) } outputFilePath := "C:\\temp\\encryptionOutput6.txt" inputFilePath := "C:\\temp\\input.mkv" EncryptFile(streamingAEAD, inputFilePath, outputFilePath, keysetAssociatedData) DecryptFile(streamingAEAD, outputFilePath, "c:\\temp\\f_result.mkv", keysetAssociatedData)
经过调查并获得 Tink 开发人员的帮助后,我发现 Tink 目前仅支持 Aead KEK URI。因此,如果您打算使用流机制,则需要将密钥集存储在某处。有关全面的讨论,请参考以下链接:https://github。 com/tink-crypto/tink-go/issues/8
