NOTE: This assembly ONLY works under the Windows operating system. All classes inside this assembly should NEVER be used directly by any application. This also means you should never link this assembly with others assemblies. In order to use theses cryptographic implementations you must change your machine.config file to redirect default implementation to the one provided in this assembly. Example: This example will replace the default RandomNumberGenerator implementation (the one used for generating keys and IV) by one using CryptoAPI. Note that there may be multiple entries to modify for a default implementation (like 3 for RNG). </configuration> ... other config stuff ... <mscorlib> <cryptographySettings> <cryptoNameMapping> <cryptoClasses> <cryptoClass CapiRNG="Mono.Security.Cryptography.RNGCryptoServiceProvider, Mono.Security.Win32, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756"/> </cryptoClasses> <nameEntry name="RandomNumberGenerator" class="CapiRNG" /> <nameEntry name="System.Security.Cryptography.RandomNumberGenerator" class="CapiRNG" /> <nameEntry name="System.Security.Cryptography.RNGCryptoServiceProvider" class="CapiRNG"/> </cryptoNameMapping> </cryptographySettings> </mscorlib> </configuration> Note: the whole <mscorlib> section can be missing from your machine.config file.
