Public Class AESEncryption

' 使用 AES-128-CBC 模式，密钥长度需为16字节（128位）

Private Shared key As Byte() = Encoding.UTF8.GetBytes("0123456789abcdef") ' 密钥示例，需与Java端一致

Private Shared iv As Byte() = Encoding.UTF8.GetBytes("1234567890abcdef") ' 初始化向量（IV）示例

' 加密方法

Public Shared Function EncryptJWM(plainText As String) As String

Using aesAlg As System.Security.Cryptography.Aes = System.Security.Cryptography.Aes.Create()

aesAlg.Key = key

aesAlg.IV = iv

aesAlg.Mode = System.Security.Cryptography.CipherMode.CBC

aesAlg.Padding = System.Security.Cryptography.PaddingMode.PKCS7

Dim encryptor As System.Security.Cryptography.ICryptoTransform = aesAlg.CreateEncryptor()

Dim plainBytes As Byte() = Encoding.UTF8.GetBytes(plainText)

Using msEncrypt As New IO.MemoryStream()

Using csEncrypt As New System.Security.Cryptography.CryptoStream(msEncrypt, encryptor, System.Security.Cryptography.CryptoStreamMode.Write)

csEncrypt.Write(plainBytes, 0, plainBytes.Length)

csEncrypt.FlushFinalBlock()

End Using

Return Convert.ToBase64String(msEncrypt.ToArray())

End Using

End Function

' 解密方法

Public Shared Function DecryptJWM(cipherText As String) As String

Dim cipherBytes As Byte() = Convert.FromBase64String(cipherText)

Using aesAlg As System.Security.Cryptography.Aes = System.Security.Cryptography.Aes.Create()

aesAlg.Key = key

aesAlg.IV = iv

aesAlg.Mode = System.Security.Cryptography.CipherMode.CBC

aesAlg.Padding = System.Security.Cryptography.PaddingMode.PKCS7

Dim decryptor As System.Security.Cryptography.ICryptoTransform = aesAlg.CreateDecryptor()

Using msDecrypt As New IO.MemoryStream(cipherBytes)

Using csDecrypt As New System.Security.Cryptography.CryptoStream(msDecrypt, decryptor, System.Security.Cryptography.CryptoStreamMode.Read)

Using srDecrypt As New IO.StreamReader(csDecrypt, Encoding.UTF8)

Return srDecrypt.ReadToEnd()

End Using

End Function

End Class

这段代码在旧版本的foxtable中无法编译，会报错图片点击可在新窗口打开查看

有什么解决方法吗

没有办法，使用其它加密方法

搞定了搞定了我自己生成了一个dll导入就行了
