-- 作者:tianhao0817 -- 发布时间:2022/12/12 19:42:00 -- 再麻烦老师看一下这段代码放到狐表里要怎么改 ,老师请看一下是不是要引用这两个DLL文件
官方的文档这里有个坑,如果你直接用是会报错的 所以需要引用一个包 Imports Org.BouncyCastle.Crypto.Engines Imports Org.BouncyCastle.Crypto.Modes Imports Org.BouncyCastle.Crypto.Parameters Imports System Imports System.Collections.Generic Imports System.Linq Imports System.Text Imports System.Threading.Tasks Namespace test1.WeiXinPay.Tools Public Class AesGcmHelper Private Shared ALGORITHM As String = "AES/GCM/NoPadding" Private Shared TAG_LENGTH_BIT As Integer = 128 Private Shared NONCE_LENGTH_BYTE As Integer = 12 Private Shared AES_KEY As String = "12345678901234567890qwertyuiopas" Public Shared Function AesGcmDecrypt(ByVal associatedData As String, ByVal nonce As String, ByVal ciphertext As String, ByVal APIV3Key As String) As String Dim gcmBlockCipher As GcmBlockCipher = New GcmBlockCipher(New AesEngine()) Dim aeadParameters As AeadParameters = New AeadParameters(New KeyParameter(Encoding.UTF8.GetBytes(APIV3Key)), 128, Encoding.UTF8.GetBytes(nonce), Encoding.UTF8.GetBytes(associatedData)) gcmBlockCipher.Init(False, aeadParameters) Dim data As Byte() = Convert.FromBase64String(ciphertext) Dim plaintext As Byte() = New Byte(gcmBlockCipher.GetOutputSize(data.Length) - 1) {} Dim length As Integer = gcmBlockCipher.ProcessBytes(data, 0, data.Length, plaintext, 0) gcmBlockCipher.DoFinal(plaintext, length) Return Encoding.UTF8.GetString(plaintext) End Function End Class End Namespace

-- 作者:有点蓝 -- 发布时间:2022/12/12 20:20:00 -- 把BouncyCastle.Crypto.dll复制到Foxtable安装目录,然后添加引用 把Namespace test1.WeiXinPay.Tools及上面的代码去掉,把Public Class AesGcmHelper以及里面的代码补全命名空间,比如:Dim gcmBlockCipher As Org.BouncyCastle.Crypto.Modes.GcmBlockCipher = New Org.BouncyCastle.Crypto.Modes.GcmBlockCipher(New AesEngine()) 然后放到全局代码。命令窗口调用参考: dim 结果 as string = AesGcmHelper.AesGcmDecrypt(传入需要的参数) msgbox(结果)
