java.lang.Enum<COSEAlgorithmIdentifier>

com.yubico.webauthn.data.COSEAlgorithmIdentifier

All Implemented Interfaces:

Serializable, Comparable<COSEAlgorithmIdentifier>, Constable

public enum COSEAlgorithmIdentifier
extends Enum<COSEAlgorithmIdentifier>

A number identifying a cryptographic algorithm. The algorithm identifiers SHOULD be values registered in the IANA COSE Algorithms registry, for instance, -7 for "ES256" and -257 for "RS256".

Method Details

values

public static COSEAlgorithmIdentifier[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static COSEAlgorithmIdentifier valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

fromId

public static Optional<COSEAlgorithmIdentifier> fromId(long id)

Attempt to parse an integer as a COSEAlgorithmIdentifier.

Parameters:

id - an integer equal to the id of a constant in COSEAlgorithmIdentifier

Returns:

The COSEAlgorithmIdentifier instance whose id equals id , if any.

See Also:

• §5.8.5. Cryptographic Algorithm Identifier (typedef COSEAlgorithmIdentifier)

fromPublicKey

public static Optional<COSEAlgorithmIdentifier> fromPublicKey(@NonNull
 @NonNull ByteArray publicKeyCose)

Read the COSEAlgorithmIdentifier from a public key in COSE_Key format.

Parameters:

publicKeyCose - a public key in COSE_Key format.

Returns:

The alg of the publicKeyCose parsed as a COSEAlgorithmIdentifier, if possible. Returns empty if the COSEAlgorithmIdentifier enum has no constant matching the alg value.

Throws:

IllegalArgumentException - if publicKeyCose is not a well-formed COSE_Key.

getId

public long getId()
