Quantum computing and its threat on encryption and our data WIRED UK. Untitled-1.
There have been more measured responses, such as the NSAs call last year to start planning to shift to quantum-resistant encryption, while the National Institute for Standards and Technology NIST is running a competition to spur work on post-quantum algorithms.

Encrypted communications are everywhere on the internet, from online banking to secure website connections to WhatsApp and iMessage. But the technology has also been criticised for allowing terrorists to communicate secretly, plotting attacks in safety that wouldnt have been possible when they communicated by post or telephone. What is encryption? Fundamentally, encryption is the act of scrambling communication.
What is encryption? Definition from WhatIs.com.
For example, there have been suspicions that interference from the National Security Agency weakened the Data Encryption Standard algorithm, and following revelations from former NSA analyst and contractor Edward Snowden, many believe the NSA has attempted to subvert other cryptography standards and weaken encryption products.

Data Encryption and Decryption Microsoft Docs.
The goal of every encryption algorithm is to make it as difficult as possible to decrypt the generated ciphertext without using the key. If a really good encryption algorithm is used, there is no technique significantly better than methodically trying every possible key.

How to encrypt almost anything PCWorld.
Most forms of encryption require you to set a password, which allows you to encrypt the file and to decrypt it later on when you want to view it again. If you use a weak password, a hacker can break the encryption and access the filedefeating the purpose of encryption.
How Encryption Works HowStuffWorks.
But the most popular forms of security all rely on encryption, the process of encoding information in such a way that only the person or computer with the key can decode it. In this article, you will learn about encryption and authentication.

What Is Data Encryption? Digital Guardian.
While symmetric-key encryption is much faster than asymmetric encryption, the sender must exchange the encryption key with the recipient before he can decrypt it. As companies find themselves needing to securely distribute and manage huge quantities of keys, most data encryption services have adapted and use an asymmetric algorithm to exchange the secret key after using a symmetric algorithm to encrypt data.

Encryption Wikipedia.
For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. It is in principle possible to decrypt the message without possessing the key, but, for a well-designed encryption scheme, considerable computational resources and skills are required.

Considering most Android, Apple and Windows apps have at least 128-bit Advanced Encryption Standard AES the standard US Government encryption algorithm for data encryption you can imagine that a 128-bit key, which has more than 300000000000000000000000000000000000, key combinations, is exceptionally safe.
