Method Detail

getAlgorithm

String getAlgorithm()

Returns the JWS alg (algorithm) header value or null if not present.

The algorithm header parameter identifies the cryptographic algorithm used to secure the JWS. Consider using SignatureAlgorithm.forName to convert this string value to a type-safe enum instance.

Returns:

the JWS alg header value or null if not present. This will always be non-null on validly constructed JWS instances, but could be null during construction.

setAlgorithm

T setAlgorithm(String alg)

Sets the JWT alg (Algorithm) header value. A null value will remove the property from the JSON map.

The algorithm header parameter identifies the cryptographic algorithm used to secure the JWS. Consider using a type-safe SignatureAlgorithm instance and using its value as the argument to this method.

Parameters:

alg - the JWS alg header value or null to remove the property from the JSON map.

Returns:

the Header instance for method chaining.

getKeyId

String getKeyId()

Returns the JWS kid (Key ID) header value or null if not present.

The keyId header parameter is a hint indicating which key was used to secure the JWS. This parameter allows originators to explicitly signal a change of key to recipients. The structure of the keyId value is unspecified.

When used with a JWK, the keyId value is used to match a JWK keyId parameter value.

Returns:

the JWS kid header value or null if not present.

setKeyId

T setKeyId(String kid)

Sets the JWT kid (Key ID) header value. A null value will remove the property from the JSON map.

The keyId header parameter is a hint indicating which key was used to secure the JWS. This parameter allows originators to explicitly signal a change of key to recipients. The structure of the keyId value is unspecified.

When used with a JWK, the keyId value is used to match a JWK keyId parameter value.

Parameters:

kid - the JWS kid header value or null to remove the property from the JSON map.

Returns:

the Header instance for method chaining.
