下面是一个使用 Delphi 实现 ECB 模式的 AES 加密的示例代码:
```delphi
unit AesEcb;
interface
uses
SysUtils, Classes;
function AesEncryptECB(const Input, Key: AnsiString): AnsiString;
function AesDecryptECB(const Input, Key: AnsiString): AnsiString;
implementation
uses
Windows, AES;
function AesEncryptECB(const Input, Key: AnsiString): AnsiString;
var
Cipher: TAES;
Output, IV: TBytes;
Data: TBytes;
Size: Integer;
begin
Cipher := TAES.Create;
try
Cipher.Mode := cmECB;
Cipher.KeySize := ks256;
Cipher.Key := Key;
SetLength(IV, Cipher.BlockSize);
FillChar(IV[0], Cipher.BlockSize, 0);
Cipher.IV := IV;
Data := TEncoding.UTF8.GetBytes(Input);
Size := Cipher.Encrypt(Data, Output);
SetLength(Output, Size);
Result := TEncoding.Base64.EncodeBytesToString(Output);
finally
Cipher.Free;
end;
end;
function AesDecryptECB(const Input, Key: AnsiString): AnsiString;
var
Cipher: TAES;
Output, IV: TBytes;
Data: TBytes;
Size: Integer;
begin
Cipher := TAES.Create;
try
Cipher.Mode := cmECB;
Cipher.KeySize := ks256;
Cipher.Key := Key;
SetLength(IV, Cipher.BlockSize);
FillChar(IV[0], Cipher.BlockSize, 0);
Cipher.IV := IV;
Data := TEncoding.Base64.DecodeStringToBytes(Input);
Size := Cipher.Decrypt(Data, Output);
SetLength(Output, Size);
Result := TEncoding.UTF8.GetString(Output);
finally
Cipher.Free;
end;
end;
end.
```
此示例代码使用了名为 `AES` 的第三方库,你需要将其添加到你的项目中。你可以从 `https://github.com/kzahel/AES` 下载该库的源代码并编译它。
