Here's what's happening: The GCM takes the plaintext as a byte string of size N, and generates a ciphertext which is a byte string of size N+28, where 12 of the 28 is the nonce, and the other 16 is the authentication tag.

If the data in the last block are insufficient to fill a block, additional padding bits must be provided. .NET does that for you by default using PKCS7; by setting Padding to PaddingMode.None, you are telling .NET that you will provide the padding yourself, but at that point the algorithm expects an input that is an exact Stupid question I know. But I have looked for HOURS on examples of how to do this. Every single example I can find uses streamwriter or streamreader which reads and writes text, not byte arrays.

Безопасность) необходимо в случае взлома хранилища. 2014/10/16 The common language runtime uses a stream-oriented design for cryptography. The core of this design is CryptoStream. Any cryptographic objects that implement CryptoStream can be chained together with any objects that implement Stream, so the streamed output from one object can be fed into the input of another object.
