It is not the answer. What are the building blocks for encryption? 1) An cryptographic algorithm 2) Some form of key generation 3) A software implementation of 1) and 2) 4) A binary distribution of 3) 5) A computer that executes 4) In practice, chances are those 5 are all rigged. They are rigged because you have so far trusted: - That there are no tricks in the algorithm or its practical implementation - That there are no tricks in the key generation algorithm or its practical implementation - Hundreds of contributors to the software implementation of those algorithms - The guy that compiled the software into binary form and distributed it - The compiler used to compile the software and all the libraries and dependencies the software has - Hardware manufacturers So, common sense tells me that because you have trusted so many people, in practice, it is very unlikely you can have end-to-end encryption or any real ambition to have privacy. This does not even consider more aspects, like your operating system, your sources of entropy, etc.
