Encryption is the method by which information is converted into secret code that hides the information's true meaning. The science of encrypting and decrypting information is called cryptography. In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext.
In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Only authorized parties can decipher a ciphertext back to plaintext and access the original information. A secure telephone is a telephone that provides voice security in the form of end-to-end encryption for the telephone call, and in some cases also the mutual authentication of the call parties, protecting them against a man-in-the-middle attack. Encrypted messaging (also known as secure messaging) provides end-to-end encryption for user-to-user text messaging. Encrypted messaging prevents anyone from monitoring your text conversations. Many encrypted messaging apps also offer end-to-end encryption for phone calls made using the apps, as well as for files that are sent using the apps. Encryption Is a One-Way Street; There’s No Going Back . If you turn on encryption for your Android phone or tablet, there’s usually no way to reverse the process, short of doing a factory reset of the device and starting over.

With recent N.S.A. revelations we know that our phone lines and almost all digital communications are tapped. Encrypting phone calls is extremely vital, and will only continue to become more important as time goes on. Dec 24, 2015 · Encryption is a process in which a message or a piece of information is encoded in such a way that only authorized parties can read it. When data is encrypted a randomly generated key is associated with it, which is needed to decrypt the message in readable form. Without the encryption key unauthorized person or device cannot decrypt the data.
The most secure kind of communications encryption, called "end-to-end" encryption, prevents even app makers, cellular carriers or phone makers from being able to read the messages.
Jul 28, 2016 · Encryption stores your phone’s data in an unreadable, seemingly scrambled form. (To actually perform the low-level encryption functions, Android uses dm-crypt, which is the standard disk encryption system in the Linux kernel.
To "Encrypt device", which will encrypt your phone memory while "Encrypt SD card" which will encrypt your external memory. Now tap to make a selection. 4. Here I tapped on "Encrypt device", but as my battery is less than 80%, I am not allowed to proceed. You can see that the "Encrypt Device" option is greyed out. When the battery is above 80%
Encrypting a cell phone often means to add a password to protect your mobile phone away from the access of some unwanted or not permitted persons. What is encryption? A fancy word for a basic concept, encryption is the science behind protecting any information stored on an electronic device, be it a phone, a laptop or a server.
