![]() The outdated data encryption standard (DES) has been replaced by modern encryption algorithms that play a critical role in the security of IT systems and communications. The purpose of data encryption is to protect digital data confidentiality as it is stored on computer systems and transmitted using the internet or other computer networks. Two main types of data encryption exist - asymmetric encryption, also known as public-key encryption, and symmetric encryption. Currently, encryption is one of the most popular and effective data security methods used by organizations. Encrypted data is commonly referred to as ciphertext, while unencrypted data is called plaintext. Data encryption translates data into another form, or code, so that only people with access to a secret key (formally called a decryption key) or password can read it. ![]()
