Encryption Techniques

Encryption techniques are methods used to secure information by converting it into a code that only authorized users can read. Imagine sending a letter in a foreign language that only the recipient understands. Common techniques include symmetric encryption, where the same key is used to encrypt and decrypt, and asymmetric encryption, which uses a pair of keys (one public and one private). These techniques protect sensitive data, like passwords and financial transactions, from unauthorized access, ensuring privacy and security in our increasingly digital world.
