public class KeyFingerprinting
extends Object

A helper method which simplifies the task of producing and comparing fingerprints of keys

Method Summary

Methods

Modifier and Type	Method and Description
static String	fingerprint(byte[] derEncoded) Produces a fingerprint encoded in the standard key fingerprint method (with : characters separating each pair of hexidecimal digits)
static String	fingerprint(KeyPair keypair) Returns a fingerprint of the private key of this keypair
static String	fingerprint(PrivateKey key) Returns a fingerprint of a private key
static String	fingerprint(PublicKey key) Returns a fingerprint of a public key (included for completeness)
static boolean	fingerprintsEqual(String hexA, String hexB) Determines whether two fingerprints are equivalent This method is useful in the case where one or more fingerprints are coming from an external source (and therefore it may or may not have : delimiters)

Method Detail

fingerprint

public static String fingerprint(KeyPair keypair)

Returns a fingerprint of the private key of this keypair

Parameters:

keypair -

Returns:

a fingerprint encoded in the standard key fingerprint method (with : characters separating each pair of hexidecimal digits)

fingerprint

public static String fingerprint(PrivateKey key)

Returns a fingerprint of a private key

Parameters:

key -

Returns:

a fingerprint encoded in the standard key fingerprint method (with : characters separating each pair of hexidecimal digits)

fingerprint

public static String fingerprint(PublicKey key)

Returns a fingerprint of a public key (included for completeness)

Parameters:

key -

Returns:

a fingerprint encoded in the standard key fingerprint method (with : characters separating each pair of hexidecimal digits)

fingerprint

public static String fingerprint(byte[] derEncoded)

Produces a fingerprint encoded in the standard key fingerprint method (with : characters separating each pair of hexidecimal digits)

Parameters:

derEncoded -

Returns:

a fingerprint encoded in the standard key fingerprint method (with : characters separating each pair of hexidecimal digits)

fingerprintsEqual

public static boolean fingerprintsEqual(String hexA,
                        String hexB)

Determines whether two fingerprints are equivalent
This method is useful in the case where one or more fingerprints are coming from an external source (and therefore it may or may not have : delimiters)

Parameters:

hexA - A series of hexidecimal characters, optionally with : separators between two-digit pairs

hexB - A series of hexidecimal characters, optionally with : separators between two-digit pairs

Returns:
