The following are top voted examples for showing how to use java. What's the Difference Between Encryption and Authentication? Encryption is the process of rendering a message such that it becomes unreadable without possessing the correct key. Santrel Media Recommended for you. Government's export restrictions on cryptographic technology limited the key size. Once the biometric authentication is compromised, it is compromised forever. The key must be provided to passport as a byte array, but for convenience (and because Google Authenticator requires so), we store it as a BASE32 encoded string. Whenever the server is authenticated, the channel is secure against man-in-the-middle attacks, but completely anonymous sessions are inherently vulnerable to such. 15 == === Changes since 1. Then, sign up or sign in a user with one of the following methods: Finally, call getCurrentUser () to get a FirebaseUser object, which contains information about the signed-in user.
