Ok boss, got it. When I solve the problem of shooting myself Ill post it here. 🙂

Ah you used LockBox component... what a shame! Real professionals don't use other people's components they make their own. But it's OK, it works.

Thanks teacher 🙂

Should not use FileStream or MemoryStream, no stream at all, just readblock - encrypt block - write block

Ok thanks I think the problem with the above code is that it gives whole file buffer as input while only 16 B is acceptable. Thats why it takes first 16 B and the rest throws away. The right way should be ReadBlock 16 by 16 B until EOF and perform readblock 16B - encrypt 16B - write 16 B until EOF.

This doesnt work: var Source, Dest: TFileStream; SrcFile, DestFile: string; Start, Stop: cardinal; Size: integer; SourceKey,NewKey: AESBlock; Key: AES128Key; SrcBuf, DstBuf: array [0..16383] of byte; SrcSize, DstSize: integer; MyInBlock, MyOutBlock: AESBlock; begin Source := TFileStream.Create(txtFile.Text, fmOpenRead); DestFile := ExtractFilePath(Application.ExeName) + 'aestemp.enc'; Dest := TFileStream.Create(DestFile, fmCreate); try Size:=Source.Read(SourceKey,SizeOf(SourceKey)); if Size<>SizeOf(SourceKey) then raise Exception.Create('Unable to read SourceKey from file.'); FillChar( Key, SizeOf(Key), 0 ); Move( PAnsiChar(AnsiString(txtPassword.Text))^, Key, Min( SizeOf( Key ), Length( txtPassword.Text ) )); //FillChar( MyInBlock, SizeOf(MyInBlock), 0 ); //Move(Source.ReadBuffer(SrcBuf,Size), MyInBlock, Min( SizeOf( MyInBLock ), Size )); NewKey:=AES128Cipher(SourceKey,Key); Dest.WriteBuffer(NewKey,SizeOf(NewKey)); //AES128Cipher(Source,Key) //Dest.WriteBuffer(AES128Cipher(Source,Key),Size); finally Dest.Free; Source.Free; end; showmessage('Finished');

Yes, but its component. Is there any standalone unit? Like this one: https://github.com/stijnsanders/tools - has standalone units in crypto folder, but unfortunately they do not produce accurate results: https://github.com/stijnsanders/tools/tree/master/crypto https://github.com/stijnsanders/tools/blob/master/crypto/aes.pas - when encrypting binary file I get only 16 B file back. But no error when building/compiling.

Hello, Can someone tell me how to set Lazarus to build for Linux? When I try to set up builder is gives some error that that system.ppu for this target (Linux) was not found. Maybe some libraries for Linux are missing? Where to get them? How to set this up properly?
