Encryption is a fundamental security process used to protect the confidentiality of information by converting it into a code to prevent unauthorized access.

It uses cryptographic algorithms and keys to transform readable data (plaintext) into an encrypted form (ciphertext). Only those who possess a specific key can decrypt and access the original content.

There are two main types of encryption: symmetric (where the same key is used to encrypt and decrypt) and asymmetric (where different keys are used: a public key to encrypt and a private key to decrypt).

Encryption is essential in today’s digital age, guaranteeing the security of data transmission, protecting stored information and complying with privacy regulations and standards.
