KeyStorage class abstract

The interface for platform-specific private key persistance.

The implementation should use OS level encrypted storage. It should not be accessible to other applications or users because it will store the private keys of the user, which is required for write operations in the chain.

EncryptedSharedPreferences should be used for Android. AES encryption is another option with AES secret key encrypted with RSA and RSA key stored in KeyStore. See https://developer.android.com/reference/androidx/security/crypto/EncryptedSharedPreferences

Keychain is recommended for iOS and MacOS. See https://developer.apple.com/documentation/security/keychain_services

For Linux libsecret is a reliable option. See https://gitlab.gnome.org/GNOME/libsecret

In JavaScript web environments the recommendation is WebCrypto with HTST enabled. See https://developer.mozilla.org/pt-BR/docs/Web/API/Web_Crypto_API

In other environments, use equivalent implementations of the recommended ones.
