我在 Delphi 2007.Net 工作,在那里我可以找到使用 Rijndael 算法的示例。
再见。
前段时间我写了这段代码,应该可以正常工作。
uses
System.Security.Cryptography,
System.Text;
type
TDynamicArrayOfByte = array of Byte;
function Encrypt(StrtoEncrypt, PK: string): TDynamicArrayOfByte; // pk, must be of a string of 32 characters
var
miRijndael: Rijndael;
encrypted: TDynamicArrayOfByte;
toEncrypt: TDynamicArrayOfByte;
bytPK: TDynamicArrayOfByte;
i: integer;
begin
Result := nil;
miRijndael := System.Security.Cryptography.RijndaelManaged.Create;
try
toEncrypt := System.Text.Encoding.UTF8.GetBytes(StrtoEncrypt);
bytPK := System.Text.Encoding.UTF8.GetBytes(PK);
miRijndael.Key := bytPK;
miRijndael.GenerateIV;
encrypted := (miRijndael.CreateEncryptor()).TransformFinalBlock(toEncrypt, 0, Length(toEncrypt));
setlength(result, Length(miRijndael.IV) + Length(encrypted));
for i:=0 to Length(miRijndael.IV)-1 do
result[i] := miRijndael.IV[i];
for i:=0 to Length(encrypted)-1 do
result[i + Length(miRijndael.IV)] := encrypted[i];
finally
miRijndael.Clear();
end;
end;
function DesEncrypt(BufferEncrypted: TDynamicArrayOfByte; PK: string): string; // pk, must be of a string of 32 characters
var
miRijndael: Rijndael;
encrypted: TDynamicArrayOfByte;
tempArray: TDynamicArrayOfByte;
bytPK: TDynamicArrayOfByte;
i : integer;
begin
Result := '';
miRijndael := System.Security.Cryptography.RijndaelManaged.Create;
setlength(tempArray, Length(miRijndael.IV));
setlength(encrypted, Length(BufferEncrypted) - Length(miRijndael.IV));
try
bytPK := System.Text.Encoding.UTF8.GetBytes(PK);
miRijndael.Key := bytPK;
for i:=0 to Length(tempArray)-1 do
tempArray[i] := BufferEncrypted[i];
for i:=0 to Length(encrypted)-1 do
encrypted[i] := BufferEncrypted[i + Length(tempArray)];
miRijndael.IV := tempArray;
Result := System.Text.Encoding.UTF8.GetString((miRijndael.CreateDecryptor()).TransformFinalBlock(encrypted, 0, Length(encrypted)));
finally
miRijndael.Clear();
end;
end;
再见。
Turbo Power LockBox,它提供对 Blowfish、RSA、MD5、SHA-1、DES、triple-DES、Rijndael和消息数字签名的支持。
Delphi Cryptography Page DCP 加密组件包含 Rijndael 算法的实现。由 David Barton (davebarton@bigfoot.com) http://www.scramdisk.clara.net/撰写,DCP Crypto 组件非常全面,可免费导出,对称密钥加密组件。
在http://rcolonel.tripod.com/有一些 delphi 源代码。你也许可以在 Delphi.net 中使用它。但是,您最好找到一个 .net 模块并使用它。您应该能够在 delphi.net 中使用 ac# 或 vb.net 模块。
