I have a question about the Win CE 7 build 1.2 (Release date: 2017-08-17) from Toradex on my Colibri IMX6DL512IT.
Using .NET Compact Framework 3.5 there is no support for SHA-256 or newer hash calculation. Only up to SHA-1 is found.
We are implementing RSA-2048 with SHA-256 digital signature, however, due to this limitation no solution is available using only .NET Compact Framework itself. I can sign data using RSA-2048 with SHA-1, but no SHA-256 seems to be available. Even if I implement a class based in HashAlgorithm class for SHA-256, it seems that Windows CE does not have support.
My question is. Does the Windows CE 7 build 1.2 supports SHA-256? Can I add support somehow?
