A) Construct a text file containing your text without the CR-LF Windows likes
and use 'TYPE'


C:\WINDOWS\Temp>dir aaa.txt
 Volume in drive C is Ice Chest
 Volume Serial Number is 3083-4508

 Directory of C:\WINDOWS\Temp

2007-08-31  16:02                 3 aaa.txt
               1 File(s)              3 bytes
               0 Dir(s)  24,640,925,696 bytes free

C:\WINDOWS\Temp>type aaa.txt | gpg --print-md sha512
8D708D18 B54DF396 2D696F06 9AD42DAD 7762B5D4 D3C97EE5 FA2DAE06 73ED4654 5164C078

B) Or use any of the versions of bash or ksh available for Win32 to get a posix
environment. There are many available: MSYS, Cygwin, UWIN, SFU/Interix

C:\WINDOWS\Temp>bash
bash-3.2$ echo -n AAA | gpg --print-md sha512
8D708D18 B54DF396 2D696F06 9AD42DAD 7762B5D4 D3C97EE5 FA2DAE06 73ED4654 5164C078
 B8DB3D59 C4B96020 E4316F17 BB3D91BF 1F6BC089 6BBE7541 6EB8C385
bash-3.2$
