Encryption is used to protect data from being stolen, changed, or compromised and works by scrambling data into a secret code that can only be unlocked with a unique digital key.
Encryption works by encoding “plaintext” into “ciphertext,” typically through the use of cryptographic mathematical models known as algorithms.
To decode the data back to plaintext requires the use of a decryption key, a string of numbers or a password also created by an algorithm. Secure encryption methods have such a large number of cryptographic keys that an unauthorized person can neither guess which one is correct, nor use a computer to easily calculate the correct string of characters by trying every potential combination (known as a brute force attack).
