Where Are Private Keys Stored Android?
Contents

A public/private key RSA pair is generated, which is stored in the Android device’s keystore and protected usually by the device PIN. An AES-based symmetric key is also generated, which is used to encrypt and decrypt the secrets.

Where are private keys stored?

If you have not yet installed your certificate, then the most likely location of your private key is on the computer or server where you generated the key pair and CSR. When you generated the key pair, you saved two files: one that contains the public key and one that contains the private key.

How do I save my secret key on Android?

When you want to store a secret, retrieve the key from KeyStore, encrypt the data with it, and then store the encrypted data in Preferences. When you want to read a secret, read the encrypted data from Preferences, get the key from KeyStore and then use the key to decrypt the data.
