What is data encryption technologies?

Data encryption technologies are methods used to translate data into an unreadable format (ciphertext). This protects the confidentiality of digital data as it is stored on computer systems and transmitted over networks. Common uses include securing sensitive information like financial records, personal data, and intellectual property, as well as protecting communications like emails and online transactions. Encryption relies on cryptographic algorithms and keys to transform data and requires the correct key to decrypt it back to its original, readable form.
