DEC 6.4 is not compatible to XE2 (and below) anymore

[Gloegg]

The current release contains a few features not supported in XE2

To Reproduce Open XE2 try to compile any 32bit project, that uses DEC (I haven't tried to compile 64bit)

Details

• In DECOptions.inc the compilerswitch {$LEGACYIFEND ON} is not available (was introduced in XE4)
• In DECCipherModesGCM.pas there are a couple places where a UInt64 variable is used in a for loop, which results in E2032 (For loop control variable must have ordinal type)
  • function TGCM.CalcGaloisHash(AuthenticatedData, Ciphertext : TBytes): T128;
  • procedure TGCM.DecodeGCM(Source, Dest: TBytes; Size: Integer);
  • procedure TGCM.EncodeGCM(Source, Dest: TBytes; Size: Integer);
• Also in DECCipherModesGCM.pas in the function TGCM.GetStandardAuthenticationTagBitLengths: TStandardBitLengths; the assignment of an array to the result gives E2010 (Incompatible types - 'TStandardBitLengths' and 'Set')

I'll have to check these. It might just take a few days as there are several things to do regarding bugfixes at the moment.

Ok, I did some changes in the development branch. Can you please check those and give feedback?

It almost works. The constant array declaration is not yet working in XE2. I created a Pull Request for the last bit to have it work with XE2. Thank you very much!
