Data encryption is the process of converting information into a code to prevent unauthorized access. It has become a vital component of data security.
In an age where data breaches are common, encryption serves as an essential barrier against data theft and loss.
1. **Symmetric Encryption**: Same key is used for encryption and decryption.
2. **Asymmetric Encryption**: Uses two keys, a public key for encryption and a private key for decryption.
Encryption algorithms transform plaintext into ciphertext, making it unreadable without the decryption key.
Understanding and implementing data encryption is crucial for protecting sensitive information and ensuring data privacy.
