sun.security.x509 .KeyIdentifier

KeyIdentifier
public class KeyIdentifier (Code)
	Represent the Key Identifier ASN.1 object. author: Amit Kapoor author: Hemma Prafullchandra version: 1.10

Constructor Summary
public	KeyIdentifier(byte[] octetString) Create a KeyIdentifier with the passed bit settings.
public	KeyIdentifier(DerValue val) Create a KeyIdentifier from the DER encoded value.
public	KeyIdentifier(PublicKey pubKey) Creates a KeyIdentifier from a public-key value.

Method Summary
void	encode(DerOutputStream out) Write the KeyIdentifier to the DerOutputStream.
public boolean	equals(Object other) Indicates whether some other object is "equal to" this one.
public byte[]	getIdentifier() Return the value of the KeyIdentifier as byte array.
public int	hashCode() Returns a hash code value for this object.
public String	toString() Returns a printable representation of the KeyUsage.

Constructor Detail

KeyIdentifier
public KeyIdentifier(byte[] octetString)(Code)
	Create a KeyIdentifier with the passed bit settings. Parameters: octetString - the octet string identifying the key identifier.

KeyIdentifier
public KeyIdentifier(DerValue val) throws IOException(Code)
	Create a KeyIdentifier from the DER encoded value. Parameters: val - the DerValue

KeyIdentifier

public KeyIdentifier(PublicKey pubKey) throws IOException(Code)

Creates a KeyIdentifier from a public-key value.

From RFC2459: Two common methods for generating key identifiers from the public key are:

The keyIdentifier is composed of the 160-bit SHA-1 hash of the value of the BIT STRING subjectPublicKey (excluding the tag, length, and number of unused bits).
The keyIdentifier is composed of a four bit type field with the value 0100 followed by the least significant 60 bits of the SHA-1 hash of the value of the BIT STRING subjectPublicKey.

This method supports method 1.
Parameters:
pubKey - the public key from which to construct this KeyIdentifier
throws:
IOException - on parsing errors

Method Detail

encode
void encode(DerOutputStream out) throws IOException(Code)
	Write the KeyIdentifier to the DerOutputStream. Parameters: out - the DerOutputStream to write the object to. exception: IOException -

equals
public boolean equals(Object other)(Code)
	Indicates whether some other object is "equal to" this one.

getIdentifier
public byte[] getIdentifier()(Code)
	Return the value of the KeyIdentifier as byte array.

hashCode
public int hashCode()(Code)
	Returns a hash code value for this object. Objects that are equal will also have the same hashcode.

toString
public String toString()(Code)
	Returns a printable representation of the KeyUsage.
