The data encryption standard uses a(n) 56-bit key.
Data encryption transforms data into another form or code so that it can only be read by those who have access to the private key (formally called the decryption key) or password. Encrypted data is commonly called ciphertext, and unencrypted data is called plaintext.
Encryption is currently one of the most popular and effective data security methods used by organizations. There are two main types of data encryption. Asymmetric and symmetric cryptography is also known as public key cryptography.
