What does encrypting personal information mean?
Encryption is a mathematical function that encodes data in such a way that only authorised users can access it. It is a way of safeguarding against unauthorised or unlawful processing of personal data, and is one way in which you can demonstrate compliance with the security principle.
How do I encrypt my Username and Password?
The Username or Password will be first encrypted using AES Symmetric key (Same key) algorithm and then will be stored in the database. The Decryption will be done by fetching the encrypted Username or Password from Database and then decrypting it using the same key that was used for encryption.
How to encrypt user data in a database?
You can use a key derivation function to convert the user’s password into an encryption key. Then you would use a cryptographically secure pseudorandom number generator to generate a separate key that would encrypt the user’s data. You would then use the derived key to encrypt the generated key.
Why do you need to store encrypted user data?
The key that actually encrypts the data is only decrypted long enough to decrypt the data that it encrypted. You’ll need to store that key in the session in order to avoid the need to ask the user for his password on each decryption occurance.
How are public and private keys used in encryption?
Asymmetric encryption uses two keys for encryption and decryption. A public key, which is shared among users, encrypts the data. A private key, which is not shared, decrypts the data. There are several types of encryption, each developed with different needs and security needs in mind.
How does symmetric encryption encrypt and decrypt data?
Symmetric encryption uses a single password to encrypt and decrypt data. Asymmetric encryption uses two keys for encryption and decryption. A public key, which is shared among users, encrypts the data. A private key, which is not shared, decrypts the data.
