Uses of PrivateKey in java.security

Methods in java.security that return PrivateKey
Modifier and Type	Method	Description
`protected abstract PrivateKey`	KeyFactorySpi.`engineGeneratePrivate(KeySpec keySpec)`	Generates a private key object from the provided key specification (key material).
`PrivateKey`	KeyFactory.`generatePrivate(KeySpec keySpec)`	Generates a private key object from the provided key specification (key material).
`PrivateKey`	KeyPair.`getPrivate()`	Returns a reference to the private key component of this key pair.
`PrivateKey`	KeyStore.PrivateKeyEntry.`getPrivateKey()`	Gets the `PrivateKey` from this entry.
