Encryption

The process of converting readable data into an encoded format that can only be decoded with the appropriate decryption key. Encryption is a fundamental security measure for protecting personal data. It works by applying mathematical algorithms to transform plaintext into ciphertext. Strong encryption uses algorithms like AES-256, proper key lengths, and secure implementation. Encryption should be applied to data at rest (stored data), data in transit (data being transmitted), and potentially data in use (data being processed). Key aspects include choosing appropriate encryption standards, securing encryption keys separately from encrypted data, implementing key management procedures, using encryption for sensitive data categories, encrypting backups, and ensuring end-to-end encryption where appropriate. Encryption protects against many breach scenarios and demonstrates security diligence. However, encryption alone doesn't ensure compliance—proper key management and access controls are equally important.
