To compile kbmMW for macOS 64 bit, you need to open kbmMW.inc, and at line 600 insert the 3 lines highlighted below:

{$IFDEF CONDITIONALEXPRESSIONS}
  // Exceptions for XE6 and XE7 which fails to compile lockfree code.
  {$IF (CompilerVersion=27) or (CompilerVersion=28)} // XE6/XE7
   {$UNDEF KBMMW_SUPPORT_LOCKFREE}
  {$IFEND}
  {$IFDEF LINUX}
   {$UNDEF KBMMW_SUPPORT_LOCKFREE}
   {$DEFINE KBMMW_PUREPASCAL}
  {$ENDIF}
  {$IFDEF OSX}
   {$DEFINE KBMMW_PUREPASCAL}
  {$ENDIF}
{$ENDIF}

Next version of kbmMW will include improvements in the kbmMW Cipher area, including support for various padding methods including automatic unpadding.

The following padding algorithms are now included:

mwpmDefault – Unchanged padding method compared to previous kbmMW Cipher releases (backwards compatible)
mwpm00 – Pad with 0
mwpmFF – Pad with $FF
mwpmSpace – Pad with $20
mwpmRandom – Pad with random data. This cannot automatically be unpadded .
mwpmISOIEC7816_4 – Pad according to ISO/IEC7816.4
mwpmPKCS_7 – Pad according to PKCS#5/PKCS#7
mwpmANSIX9_23_00 – Pad with $00 according to ANSI X9.23
mwpmANSIX9_23_Random – Pad with random data according to ANSI X9.23
