Abstract
In one example a processing device can receive an indication from a software application that an encrypted communication transmitted by a remote device is stored in a memory location. In response to receiving the indication, the processing device can retrieve the encrypted communication from the memory location, decrypt the encrypted communication using a first key to determine a decrypted version of the encrypted communication, and extract a second key from the decrypted version of the encrypted communication. The second key can be different from the first key. And the second key can be configured to decrypt a set of encrypted data stored in a non-volatile memory device that is accessible to the computing device.
