@Immutable
public class OctetSequenceKey
extends JWK

Octet sequence JSON Web Key (JWK), used to represent symmetric keys. This class is immutable.

Example JSON object representation of an octet sequence JWK:

 {
   "kty" : "oct",
   "alg" : "A128KW",
   "k"   : "GawgguFyGrWKav7AX4VKUg"
 }

OctetSequenceKey

public OctetSequenceKey(Base64URL k,
                Use use,
                Algorithm alg,
                String kid,

                Base64URL x5t,
                List<Base64> x5c)

Creates a new octet sequence JSON Web Key (JWK) with the specified parameters.

Parameters:

k - The key value. It is represented as the Base64URL encoding of value's big endian representation. Must not be null.

use - The key use. null if not specified.

alg - The intended JOSE algorithm for the key, null if not specified.

kid - The key ID. null if not specified.

x5u - The X.509 certificate URL, null if not specified.

x5t - The X.509 certificate thumbprint, null if not specified.

x5c - The X.509 certificate chain, null if not specified.

Method Detail

getKeyValue

public Base64URL getKeyValue()

Returns the value of this octet sequence key.

Returns:

The key value. It is represented as the Base64URL encoding of the coordinate's big endian representation.

toByteArray

public byte[] toByteArray()

Returns a copy of this octet sequence key value as a byte array.

Returns:

The key value as a byte array.

isPrivate

public boolean isPrivate()

Octet sequence (symmetric) keys are never considered public, this method always returns true.

Specified by:

isPrivate in class JWK

Returns:

true

toPublicJWK

public OctetSequenceKey toPublicJWK()

Octet sequence (symmetric) keys are never considered public, this method always returns null.

Specified by:

toPublicJWK in class JWK

Returns:

null

toJSONObject

public net.minidev.json.JSONObject toJSONObject()

Description copied from class: JWK

Returns a JSON object representation of this JWK. This method is intended to be called from extending classes.

Example:

 {
   "kty" : "RSA",
   "use" : "sig",
   "kid" : "fd28e025-8d24-48bc-a51a-e2ffc8bc274b"
 }
 

Overrides:

toJSONObject in class JWK

Returns:

The JSON object representation.

parse

public static OctetSequenceKey parse(String s)
                              throws ParseException

Parses an octet sequence JWK from the specified JSON object string representation.

Parameters:

s - The JSON object string to parse. Must not be null.

Returns:

The octet sequence JWK.

Throws:

ParseException - If the string couldn't be parsed to an octet sequence JWK.

parse

public static OctetSequenceKey parse(net.minidev.json.JSONObject jsonObject)
                              throws ParseException

Parses an octet sequence JWK from the specified JSON object representation.

Parameters:

jsonObject - The JSON object to parse. Must not be

Returns:

The octet sequence JWK.

Throws:

ParseException - If the JSON object couldn't be parsed to an octet sequence JWK.
