Thanks for the answer, I will use those params. Is your platform using Bouncy Castle under the hood or is it using another type of lib?

What about the MAC size? Should it be 96 bits also or 128? I ask because in the file GCMTests.cs I noticed that all the tests are made with a IV size of 128 bits and a Max Size of 128 bits also. Any help is welcome. 😊 Benoit
