Encryption

Definition

Encryption is the process of converting information or data into a code to prevent unauthorized access. This technique ensures that only those with the proper key or password can read or decrypt the information, making it crucial for secure communications and intelligence operations. It protects sensitive data from adversaries and allows for secure transmission of messages during critical times.
