What is a Keystore File?
A Keystore File (sometimes called a UTC file) in Ethereum is an encrypted version of your private key. They are generated using your private key and a password that you use to encrypt it. If you open up your keystore file in a text editor it contains data pertaining to the encryption of the private key.
