    change validation from SHA1 to HMACSHA256

    We have been using SHA1 as validation key in our machine config for our application which is hosted on Microsoft Azure with Umbraco version 7.2.8.

    Recently Microsoft upgraded their security algorithm by changing validation key as HMACSHA256 for increasing level of security.

    Due to this change, none of our existing user were able to log in to our application.

    We raised same issue with Microsoft which was ended with following conclusion -

    1. HMACSHA256 is the latest and more secure algorithm introduced by them.
    2. They have advised us to check Umbraco compatibility with HMACSHA256.

    Could you please provide us an appropriate solution.

    Thanks in Advance !!!
