The RSA cryptographic key material, including a private key and public key, is
embedded within the application package. Because Android applications can
be extracted and reverse engineered, storing private cryptographic keys
directly inside the client application may allow an attacker to recover the
keys and potentially use them to impersonate the application, decrypt protected
data, or generate unauthorized cryptographic operations.
