VB6.0实现AES/ECB/PKCS7Padding加密

根据提供的引用内容，可以了解到VB6.0实现AES/ECB/PKCS7Padding加密的方法。以下是实现步骤：

1. 首先需要引用Microsoft Enhanced Cryptographic Provider 1.0库，可以在VB6.0的工具->引用中找到该库并勾选。

2. 导入以下代码：

Private Function AESEncrypt(ByVal str As String, ByVal key As String) As String
    Dim aes As New AesCryptoServiceProvider
    aes.Mode = CipherMode.ECB
    aes.Padding = PaddingMode.PKCS7
    aes.KeySize = 128
    aes.BlockSize = 128
    aes.Key = Encoding.UTF8.GetBytes(key)
    aes.GenerateIV()
    Dim encryptor As ICryptoTransform = aes.CreateEncryptor(aes.Key, aes.IV)
    Dim data As Byte() = Encoding.UTF8.GetBytes(str)
    Dim result As Byte() = encryptor.TransformFinalBlock(data, 0, data.Length)
    Return BitConverter.ToString(result).Replace("-", "")
End Function

3. 调用该函数即可实现AES/ECB/PKCS7Padding加密，其中str为待加密的字符串，key为密钥。
