Hey everyone, Microsoft recently announced that Outlook will be launching end to end encryption, and I thought some discussion was warranted.
#1 As I understand it (correct me if I am wrong) but if I am using a extension such as Enigmail, as long as I have a person's public key then I can send them encrypted emails... the post from Microsoft says "These encrypted emails cannot be forwarded or copied, and any documents in them will remain encrypted if access by another user without an Office 365 subscription".... Does this mean they are using an office subscription as the Public key? It seems like a blatant attempt to lock people into using office 365 (what if I don't have 365, Enigmail is free if using Thunderbird which is also free)
#2 Outlook has also added a feature where it will automatically ask you if you'd like to encrypt an email if it detects sensitive information in the email such as a bank account number or social security number, the post noted... how exactly would that be accomplished?, how does it know that a certain group of numbers is sensitive information?
#3 Hypothetically would it be possible for Microsoft to put a backdoor into their end to end encryption so that if they needed to access specific emails they could if they were required to do so via a subpoena? If they did this would it be discover able through an audit, considering Windows source code is not "open source" ?
Thank you in advance to anyone that can answer the above questions
