What Is Encryption?
Encryption is the process of transforming information or data into a form that cannot be read by anyone except those who have access to a special key. It is used to protect sensitive information from unauthorized access and ensure its confidentiality, integrity, and availability. Encryption can also be used for authentication purposes, allowing only authorized users to gain access to certain resources.
Encryption works by using an algorithm (a mathematical formula) which scrambles plain text into ciphertext. This ciphertext can then only be decrypted with the correct key or password. The strength of encryption depends on the complexity of the algorithm as well as the length and randomness of the key being used. Modern encryption algorithms are extremely secure and difficult to break even with powerful computers; however, it is important that keys are kept safe in order for them not to fall into malicious hands.
