Enclosing class:
  KeyStore

    public static final class KeyStore.PrivateKeyEntry

extends Object
implements KeyStore.Entry

A `KeyStore` entry that holds a `PrivateKey` and corresponding certificate chain.

Since:

Constructor Summary
`KeyStore.PrivateKeyEntry(PrivateKey privateKey, Certificate[] chain)` Constructs a `PrivateKeyEntry` with a `PrivateKey` and corresponding certificate chain.

Method Summary
`Certificate` | `getCertificate()` Gets the end entity `Certificate` from the certificate chain in this entry.
`Certificate[]` | `getCertificateChain()` Gets the `Certificate` chain from this entry.
`PrivateKey` | `getPrivateKey()` Gets the `PrivateKey` from this entry.

Constructor Detail

### KeyStore.PrivateKeyEntry

    public KeyStore.PrivateKeyEntry(PrivateKey privateKey,
                                    Certificate[] chain)

  Constructs a `PrivateKeyEntry` with a `PrivateKey` and corresponding certificate chain.

  The specified `chain` is cloned before it is stored in the new `PrivateKeyEntry` object.

  Parameters:
    `privateKey` - the `PrivateKey`
    `chain` - an array of `Certificate`s representing the certificate chain. The chain must be ordered and contain a `Certificate` at index 0 corresponding to the private key.
  Throws:
    `NullPointerException` - if `privateKey` or `chain` is `null`
    `IllegalArgumentException` - if the specified chain has a length of 0, if the specified chain does not contain `Certificate`s of the same type, or if the `PrivateKey` algorithm does not match the algorithm of the `PublicKey` in the end entity `Certificate` (at index 0)

Method Detail

### getPrivateKey

    public PrivateKey getPrivateKey()

  Gets the `PrivateKey` from this entry.

  Returns:
    the `PrivateKey` from this entry

### getCertificateChain

    public Certificate[] getCertificateChain()

  Gets the `Certificate` chain from this entry.

  The stored chain is cloned before being returned.

  Returns:
    an array of `Certificate`s corresponding to the certificate chain for the public key. If the certificates are of type X.509, the runtime type of the returned array is `X509Certificate[]`.

### getCertificate

    public Certificate getCertificate()

  Gets the end entity `Certificate` from the certificate chain in this entry.

  Returns:
    the end entity `Certificate` (at index 0) from the certificate chain in this entry. If the certificate is of type X.509, the runtime type of the returned certificate is `X509Certificate`.

### toString

    public String toString()

  Returns a string representation of this PrivateKeyEntry.

  Overrides:
    `toString` in class `Object`
  Returns:
    a string representation of this PrivateKeyEntry.
