Where is the class CryptoCommon in xamarin

Im trying to use the CryptoCommon class but unable the find it in the monotuch assembly.

I found the assembly Mono.Security.Cryptography, does it have the same performance as the CryptoCommon class?

Thanks!!

Solution

  • CommonCrypto is used internally inside Xamarin.iOS, this is not something extra - i.e. there's no need to opt-in or opt-out.

    What it means is that it's use is totally transparent to your code. If an algorithm is available in CommonCrypto then using the classic .NET type will use it.

    E.g.

    // this will use CommonCrypto. AES is supported by CommonCrypto
// if your device supports it AES can be hardware accelerated
var aes = Aes.Create (); 

// this will also use CommonCrypto. SHA-1 is supported by CommonCrypto
// if your device supports it SHA-1 can be hardware accelerated
var sha = new SHA1Managed (); 

// this will not use CommonCrypto since the algorithm is not supported by Apple
var r = RIPEMD160.Create ();

    More information about CommonCrypto can be found on my blog.
