Types of Encryption, Methods & Use Cases

eSecurity Planet

Encryption scrambles data to make it unreadable to those without decryption keys. Proper use of encryption preserves secrecy and radically lowers the potential damage of a successful cybersecurity attack. Encryption algorithm types will provide an overview of the mathematical algorithms used to encrypt data (AES, RSA, etc.),

Everything Encrypted Will Soon Become Decryptable: We Must Prepare Now For The Era Of Quantum Computers

Joseph Steinberg

Nearly every piece of data that is presently protected through the use of encryption may become vulnerable to exposure unless we take action soon. While quantum computers already exist, no devices are believed to yet exist that are anywhere near powerful enough to crack modern encryption in short order.
