Questions tagged [encryption]
Encryption is the process of transforming information (called plaintext) into an unreadable form (called ciphertext) using an encryption algorithm using a secondary parameter (called an encryption key). Only those who possess the decryption key can easily reverse the process and recover the original plaintext. Conceptual questions about encryption may get better answers on crypto.stackexchange.com.
