Systems, methods, and software can be used to encrypt and decrypt data. In some aspects, a first primary secret key based on a primary ephemeral key pair and a primary master public key is generated by a primary data service application on an electronic device. A first primary ciphertext is generated by encrypting a first portion of the data using the first primary secret key. A second primary secret key is generated based on the first primary secret key. The first primary secret key is deleted. The first primary ciphertext is sent from the primary data service application to a secondary data service application. A first encrypted text is received from the secondary data service application. The first encrypted text is generated by encrypting the first primary ciphertext.
