Delphi7 MD5 加密

引用三个单元，分别是：IdHashMessageDigest,IdGlobal, IdHash;

 1 uses IdHashMessageDigest,IdGlobal, IdHash;
 2 
 3 vars:string;
 4 MyMD5: TIdHashMessageDigest5;
 5 Digest: T4x4LongWordRecord;
 6 begin
 7 s:='123456';
 8 MyMD5 := TIdHashMessageDigest5.Create;
 9 Digest := MyMD5.HashValue(s);
10 s:=MyMD5.AsHex(Digest);
11 end;
