A strategy to establish trustworthiness of certificates without consulting the trust manager configured in the actual SSL context. This interface can be used to override the standard JSSE certificate verification process.

Security Warning

If a trust strategy considers a certificate chain to be trusted, then the default trust manager will not be consulted. Trust strategy implementations should therefore consider properly checking the complete certificate chain. Checking for example only the subject of a certificate does not protect against man-in-the-middle attacks. For self-signed certificates prefer specifying a keystore containing the certificate chain when calling the SSLContextBuilder loadTrustMaterial methods instead of implementing a custom trust strategy.

A trust strategy alone cannot be used for certificate pinning. When isTrusted returns false the certificate check falls back to the trust manager which might consider the certificate trusted. See the isTrusted(X509Certificate[], String) documentation.
