Hello guys!
I'm converting my project to 64-bit and I'm having an exception when initialising System.Security.Cryptography.HMACSHA256. This was working in the 32-bit version.
NullReferenceException: A null value was found where an object instance was required.
at System.Security.Cryptography.KeyedHashAlgorithm.set_Key (System.Byte[] value) [0x00000]
Do you know what's the problem and how can I solve it?
