Data encryption is a method to protect your data whereby you convert your data from plaintext to encoded ciphertext format using the encryption key. To read these ciphertexts, they first need to be decrypted using the encryption key, and only authorized users will have access to those decryption keys. Commonly used key-based encryption falls into one of two categories of cryptography:
- Symmetric-key encryption: With symmetric encryption algorithms, the same key is used to encrypt and decrypt the data. Each data packet is self-encrypted with a secret key. Data is encrypted while saving and decrypted during retrieval. Earlier, symmetric encryption used to be applied as per the Data Encryption Standard (DES), which used a 56-bit key. Now, the Advanced Encryption Standard (AES) is heavily used for symmetric encryption, which is more reliable as it uses a 128-bit, 192-bit, or 256-bit key.
- Asymmetric-key encryption: With the help of asymmetric algorithms, two different keys...
