Hashing plugin won't load up in Optiklink but when I tried the same script and plugins from localhost it works. In Optiklink, some random error pops up due to hashing plugin and makes the registration system unusable. The error is :
Plugin error >> dlopen() 'plugins/hashing04rel64.so' failed: plugins/hashing04rel64.so: undefined symbol: _ZN8CryptoPP6Filter11TransferTo2ERNS_22BufferedTransformationERyRKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEb
I've tried 32-bit also but it ends with different error.
Nevermind. I found the solution. Replace the default hashing04rel64.so with this file:
