LockBox3 DecryptStream können Normalstrom nicht schaffen

Question

Wenn ich versuche, einige binäre Daten alles gut funktioniert zu kodieren:

void __fastcall TForm1::EncryptBtnClick(TObject *Sender) 
{ 
    char plainchar[16]={0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x0A,0x0B,0x0C,0x0D,0x0E,0x0F}; 
    char keychar[16]={0xE8,0xE9,0xEA,0xEB,0xED,0xEE,0xEF,0xF0,0xF2,0xF3,0xF4,0xF5,0xF7,0xF8,0xF9,0xFA}; 
    char chiperchar[16]; 

    TMemoryStream *plainStream; 
    TMemoryStream *chiperStream; 
    TMemoryStream *keyStream; 

    plainStream = new TMemoryStream(); 
    chiperStream = new TMemoryStream(); 
    keyStream = new TMemoryStream(); 

    plainStream->Clear(); 
    plainStream->Position=0; 
    plainStream->WriteBuffer(plainchar,16); 
    plainStream->Position=0; 

    keyStream->Clear(); 
    keyStream->Position=0; 
    keyStream->WriteBuffer(keychar,16); 
    keyStream->Position=0; 
    Codec1->Reset(); 
    Codec1->InitFromStream(keyStream); 

    Codec1->EncryptStream(plainStream,chiperStream); 

    chiperStream->Position=0; 
    chiperStream->ReadBuffer(chiperchar,16); 

    plainStream->Free(); 
    chiperStream->Free(); 
    keyStream->Free(); 
} 

Und ich erwartet erhalten

0x3E,0x45,0xC2,0x15,0xBA,0x45,0x0E,0xA6,0xEF,0x94,0xA3,0x08,0x82,0xB8,0x1B,0xD4 

in chiperchar Puffer.

Leider, wenn ich versuche DecryptStream Funktion für über chiper Puffer zu verwenden, ist es nicht glatt Datenstrom schafft (Strom ist 0 Byte Länge)

void __fastcall TForm1::DecryptBtnClick(TObject *Sender) 
{ 
char chiperchar[16]={0x3E,0x45,0xC2,0x15,0xBA,0x45,0x0E,0xA6,0xEF,0x94,0xA3,0x08,0x82,0xB8,0x1B,0xD4}; 
char keychar[16]={0xE8,0xE9,0xEA,0xEB,0xED,0xEE,0xEF,0xF0,0xF2,0xF3,0xF4,0xF5,0xF7,0xF8,0xF9,0xFA}; 
char plainchar[16]; 

TMemoryStream *plainStream; 
TMemoryStream *chiperStream; 
TMemoryStream *keyStream; 

plainStream = new TMemoryStream(); 
chiperStream = new TMemoryStream(); 
keyStream = new TMemoryStream(); 

chiperStream->Clear(); 
chiperStream->Position=0; 
chiperStream->WriteBuffer(chiperchar,16); 
chiperStream->Position=0; 

keyStream->Clear(); 
keyStream->Position=0; 
keyStream->WriteBuffer(keychar,16); 
keyStream->Position=0; 
Codec1->Reset(); 
Codec1->InitFromStream(keyStream); 

plainStream->Clear(); 
plainStream->Position=0; 

Codec1->DecryptStream(plainStream,chiperStream); 

plainStream->Position=0; 
chiperStream->Position=0; 

plainStream->Position=0; 
plainStream->ReadBuffer(plainchar,16); 

plainStream->Free(); 
chiperStream->Free(); 
keyStream->Free(); 
} 

Was ich dooing falsch? Warum kann DecrpytStream keinen korrekten Stream erstellen?

Wenn ich EncryptString und DecryptString Funktionen verwende, funktioniert alles gut, und nach der Verschlüsselung und Entschlüsselung bekomme ich die gleiche Zeichenfolge.

CODEC1 Eigenschaften sind:

AsymetricKeySizeInBits = 128 
AdvancedOptions2 = [] 
CryptoLibrary = CryptographicLibrary1 
StreamCipherId = 'native.StreamToBlock' 
BlockCipherId = 'native.AES-128' 
ChainId = 'native.ECB'

Sorry, ich weiß nicht C++ kennen. Meine Sprache ist Delphi.

Dies funktioniert ....

procedure TForm30.Button1Click(Sender: TObject); 
const 
    chiperchar: utf8string = #$3E#$45#$C2#$15#$BA#$45#$0E#$A6#$EF#$94#$A3#$08#$82#$B8#$1B#$D4; 
    keychar : utf8string = #$E8#$E9#$EA#$EB#$ED#$EE#$EF#$F0#$F2#$F3#$F4#$F5#$F7#$F8#$F9#$FA; 
var 
    plainStream, chiperStream, keyStream: TMemoryStream; 
    OriginalPlainText: string; 
    ReconstructedPlainText: string; 

begin 
    plainStream := TMemoryStream.Create; 
    chiperStream := TMemoryStream.Create; 
    keyStream := TMemoryStream.Create; 
    try 
    OriginalPlainText := 'Your lips are smoother than vasoline.'; 
    Memo1.Lines.Add('Plaintext (passed as UTF-8 encoding) = "' + OriginalPlainText + '"'); 
    TPLB3.StreamUtils.String_to_stream(OriginalPlainText, plainStream, TEncoding.UTF8); 
    Memo1.Lines.Add('Length of plaintext = ' + IntToStr(plainStream.Size) + ' bytes.'); 
    keyStream.WriteBuffer(keychar[ Low(keychar)], Length(keychar)); 
    keyStream.Position := 0; 
    Codec1.InitFromStream(keyStream); 

    Codec1.EncryptStream(plainStream, chiperStream); 
    Memo1.Lines.Add('Base64 encoding of ciphertext = ' + TPLB3.StreamUtils.Stream_to_Base64(chiperStream)); 
    Memo1.Lines.Add('Length of ciphertext = ' + IntToStr(chiperStream.Size) + ' bytes.'); 

    Codec1.Reset; 
    chiperStream.Position := 0; 
    plainStream.Size := 0; 
    Codec1.DecryptStream(plainStream, chiperStream); 
    ReconstructedPlainText := TPLB3.StreamUtils.Stream_to_string(plainStream, TEncoding.UTF8); 
    Memo1.Lines.Add('Reconstructed plaintext = "' + ReconstructedPlainText + '"'); 

    finally 
    plainStream.Free; 
    chiperStream.Free; 
    keyStream.Free; 
    end 
end;
