Per-user encryption allows you to encrypt data for a certain user. This guide shows how to encrypt and decrypt data for the end-user with PureKit.
Before you begin
To encrypt data for a
userId, PureKit provides you with the
dataId pair, PureKit generates a unique key pair. Therefore, data encryption is performed in a way only a user with the appropriate key can decrypt the data.
Here is an example of data encryption:
byte cipherText = pure.encrypt(userId, dataId, plainText)
Note that there can be multiple data IDs, e.g., if data is divided in groups. Read more on how data can be grouped here.
decrypt function to perform data decryption. This function can be used after the user has been authenticated to decrypt the encrypted data.
Here is an example of data decryption:
byte plainText = pure.decrypt(authResult.getGrant(), dataId, cipherText);
PureGrant is a token generated for the data owner during the authentication process.
Just like in the
encrypt function, there can be multiple data IDs, e.g., if data is divided in groups. Read more on how data can be grouped here.
