Words to know
- HMAC / signature
- A secret code made from the message and a secret key. If the code matches, you know the message is real and was not changed.
- A document file that looks the same on every phone and computer.
- App signing / keystore
- Every app is signed with a private key (kept in a keystore file). Updates must be signed with the same key, so never lose it.
