To fix the problem, we need to replace the NullTrustManager with a TrustManager that only trusts specific self-signed certificates. This involves creating a KeyStore containing the trusted certificates and initializing the TrustManagerFactory with this KeyStore. This way, only the specified certificates will be trusted, and the risk of a machine-in-the-middle attack is mitigated.
- Load the self-signed certificate into a
KeyStore. - Initialize a
TrustManagerFactorywith theKeyStore. - Use the
TrustManagerFactoryto get theTrustManagerarray. - Initialize the
SSLContextwith theTrustManagerarray.
