MD5 encryption is not secure

Email authentication using MD5 algorithm is considered insecure by Android. Can it be changed to SHA256?The server no longer supports MD5 encryption.

Hi @zxl13237005459 , it seems this would be a requirement in the spec. The server reads the Content-MD5 header to check the body of the message was not modified.

We cannot just add SHA256 support, because adding a new header, lets say Content-SHA256, the server needs to know that header exists, or otherwise it will ignore it.
