Select from following answers:- Use obfuscation.
- Hash the data.
- Use symmetric and asymmetric encryption

- All Above
Secret-key encryption (symmetric cryptography) performs a transformation on data to keep third parties from reading it. This type of encryption uses a single shared, secret key to encrypt and decrypt data. Encrypting before saving allows you to store the data securely.
Public-key encryption (asymmetric cryptography) performs a transformation on data to keep third parties from reading it. This type of encryption uses a public/private key pair to encrypt and decrypt data. Encrypting before saving allows you to store the data securely.
