Changing the cryptographic strength

To change the cryptographic strength simply replace the cryptography.dll file, located in <your-SDK-path>\epoc32\release\<target>\<variant>, with a version of the DLL that has the required strength. There are two crypto DLLs available for selection, see Weak and strong cryptography.

So, for example, if you wanted to increase the strength of cryptography.dll in say <your-SDK-path>\epoc32\release\wins\urel to strong_cryptography.dll, then you would do this as follows:

• Get a copy of strong_cryptography.dll from <your-SDK-path>\src\generic\security\crypto\import\bin\wins\urel

• Paste this into <your-SDK-path>\epoc32\release\wins\urel

• Rename the copied strong_cryptography.dll to cryptography.dll
