keystore

问题 What's the difference between a keystore and a truststore? 回答1: A keystore contains private keys, and the certificates with their corresponding public keys. A truststore contains certificates from other parties that you expect to communicate with, or from Certificate Authorities that you trust to identify other parties. 回答2: A keystore contains private keys. You only need this if you are a server, or if the server requires client authentication. A truststore contains CA certificates to trust.

问题 If a key store containing one or more PrivateKeyEntry is specified as a trust store, will JSSE create a trust anchor from the end-entity certificate in each of those entries? In other words, is it enough to have a certificate under a PrivateKeyEntry if we have one keystore with both trusted and private entries? Or, must we also add that certificate as a TrustedCertificateEntry ? 回答1: It doesn't matter where certificate placed either under PrivateKeyEntry or under trustedCertEntry , JVM trusts
