So am working on an application to encrypt sms messages before they are sent and decrypted on delivery as long as the message is received by the intended recipient by matching the phone no from the sender with that on the recipient's sim card. Question is?
1. How do i get the sim cards phone no. without having to send an sms to another no. which sends a reply. Trying to avoid this method Ah, how is that better than using a private key? If your information is worth protecting, someone can always figure a way to spoof the phone number after intercepting your message. And you make it easy for them for they know your key, which is the cell number of end user
The intention is to eliminate middlemen from reading messages and if they were to intercept the message it would be encrypted. 2. So how easy would it be to spoof the app?
If you can implement it, I am very certain someone can beat it. Numerous implementation done by far larger group has gone down. A better thing is to use a library of widely used encryption system like openSSL. Been vetted by a large group of cryptanalyst. Google and see if there is anybody who recommend implementing a home made encryption system. Its way too hard to do it correctly. My two cents. Muriithi
