到现在为止我对此没有任何问题，但我有一个问题，如果是 256 AES，我将使用 MCRYPT_RIJNDAEL_128 或 MCRYPT_RIJNDAEL_256
提前感谢您的帮助！
此行失败：
Base64_to_stream(aCiphertext, stmCipher);
现在，Base64_to_stream 在 TPLB3.StreamUtils 中声明如下：
procedure Base64_to_stream(const Base64: string; Destin: TStream);
如果您尝试调用 Base64_to_stream 那么您将不会看到编译错误。由于您没有在 uses 子句中包含 TPLB3.StreamUtils，因此只能假设您的一个单元定义了一个不同的 Base64_to_stream，它接受 TArray<Byte> 作为其第一个参数。
更新
根据您的单位名称和@TOndrej 提供的 link 判断，看起来您正在混合和匹配 LockBox 实现。这些单位 uTPLb_Random、uTPLb_StreamUtils 和 uTPLb_Constants 似乎都来自不同的 LockBox 实现。
我建议您查看从何处获得这些不同的 LockBox 实现。您应该只使用一个 LockBox 实现。也许您应该考虑不使用搜索路径，而是明确地将这些单元添加到您的项目中。这样您就不会意外地使用您不想使用的单位。

到现在为止我对此没有任何问题，但我有一个问题，如果是 256 AES，我将使用 MCRYPT_RIJNDAEL_128 或 MCRYPT_RIJNDAEL_256
提前感谢您的帮助！
此行失败：
Base64_to_stream(aCiphertext, stmCipher);
现在，Base64_to_stream 在 TPLB3.StreamUtils 中声明如下：
procedure Base64_to_stream(const Base64: string; Destin: TStream);
如果您尝试调用 Base64_to_stream 那么您将不会看到编译错误。由于您没有在 uses 子句中包含 TPLB3.StreamUtils，因此只能假设您的一个单元定义了一个不同的 Base64_to_stream，它接受 TArray<Byte> 作为其第一个参数。
更新
根据您的单位名称和@TOndrej 提供的 link 判断，看起来您正在混合和匹配 LockBox 实现。这些单位 uTPLb_Random、uTPLb_StreamUtils 和 uTPLb_Constants 似乎都来自不同的 LockBox 实现。
我建议您查看从何处获得这些不同的 LockBox 实现。您应该只使用一个 LockBox 实现。也许您应该考虑不使用搜索路径，而是明确地将这些单元添加到您的项目中。这样您就不会意外地使用您不想使用的单位。
