#405 De/Re-Identification fails in Windows x64

[Georgios Christodoulakis]

Dear GDCM Team,
I have installed GDCM-2.6.5 and I am trying to de-identify and then re-identify a DICOM. Unfortunately the process is not working well and I cannot find out why. I checked my key/cert pair at a Linux machine with a very old version of GDCM and the process works OK.
Below you can see the commands in my Windows 8 (x64) machine:

//------------------------------------------------------------------------------
C:\Program Files (x86)\GDCM 2.6\bin>gdcmanon -c C:\OpenSSL-Win32\bin\cert.pem -e
-r --continue C:\Users\gxristod\Downloads\Original C:\Users\gxristod\Downloads\
DeIdentified

C:\Program Files (x86)\GDCM 2.6\bin>gdcmanon -k C:\OpenSSL-Win32\bin\key.pem -d
-r C:\Users\gxristod\Downloads\DeIdentified C:\Users\gxristod\Downloads\ReIdenti
fied
Could not Re-indentify : C:\Users\gxristod\Downloads\DeIdentified/IM-0001-0001.d

Thank you!

Hi Georgios,
I had a similar probleme that happened to me on couple of computers, one on Win8, 2 others on Win10. I found that the CryptoAPI is not use properly and that it is probably the issue here. At least, it fixed my failing computers. You can find the patch attached to this answer.

Hi,

Thank you very much for the help!

I have already finished that project I was working on but I could use it
for future reference.

Best,

George
