Constructor Detail

DefaultJWEHeaderFilter

public DefaultJWEHeaderFilter(Set<JWEAlgorithm> algs,
                              Set<EncryptionMethod> encs)

Creates a new JWE header filter. The accepted algorithms and encryption methods are set to equal the specified supported ones. The accepted header parameters are set to match JWEHeader.getReservedParameterNames().

Parameters:

algs - The supported JWE algorithms. Used to bound the accepted algorithms. Must not be null.

encs - The supported encryption methods. Used to bound the accepted encryption methods. Must not be null.

DefaultJWEHeaderFilter

public DefaultJWEHeaderFilter(Set<JWEAlgorithm> algs,
                              Set<EncryptionMethod> encs,
                              Set<String> acceptedParams)

Creates a new JWE header filter. The accepted algorithms and encryption methods are set to equal the specified supported ones.

Parameters:

algs - The supported JWE algorithms. Used to bound the accepted algorithms. Must not be null.

encs - The supported encryption methods. Used to bound the accepted encryption methods. Must not be null.

acceptedParams - The accepted JWE header parameters. Must contain at least the alg and enc parameters. Must not be null.

Method Detail

supportedAlgorithms

public Set<JWEAlgorithm> supportedAlgorithms()

Returns the names of the supported JWE algorithms. Used to bound the accepted algorithms.

Returns:

The supported JWE algorithms as a read-only set, empty set if none.

getAcceptedAlgorithms

public Set<JWEAlgorithm> getAcceptedAlgorithms()

Description copied from interface: JWEHeaderFilter

Gets the names of the accepted JWE algorithms. These correspond to the alg JWE header parameter.

Specified by:

getAcceptedAlgorithms in interface JWEHeaderFilter

Returns:

The accepted JWE algorithms, as a read-only set, empty set if none.

setAcceptedAlgorithms

public void setAcceptedAlgorithms(Set<JWEAlgorithm> acceptedAlgs)

Description copied from interface: JWEHeaderFilter

Sets the names of the accepted JWE algorithms. These correspond to the alg JWE header parameter.

Specified by:

setAcceptedAlgorithms in interface JWEHeaderFilter

Parameters:

acceptedAlgs - The accepted JWE algorithms. Must be a subset of the supported algorithms and not null.

supportedEncryptionMethods

public Set<EncryptionMethod> supportedEncryptionMethods()

Returns the names of the supported encryption methods. Used to bound the accepted encryption methods.

Returns:

The supported encryption methods as a read-only set, empty set if none.

getAcceptedEncryptionMethods

public Set<EncryptionMethod> getAcceptedEncryptionMethods()

Description copied from interface: JWEHeaderFilter

Gets the names of the accepted encryption methods. These correspond to the enc JWE header parameter.

Specified by:

getAcceptedEncryptionMethods in interface JWEHeaderFilter

Returns:

The accepted encryption methods, as a read-only set, empty set if none.

setAcceptedEncryptionMethods

public void setAcceptedEncryptionMethods(Set<EncryptionMethod> acceptedEncs)

Description copied from interface: JWEHeaderFilter

Sets the names of the accepted encryption methods. These correspond to the enc JWE header parameter.

Specified by:

setAcceptedEncryptionMethods in interface JWEHeaderFilter

Parameters:

acceptedEncs - The accepted encryption methods. Must be a subset of the supported encryption methods and not null.

setAcceptedParameters

public void setAcceptedParameters(Set<String> acceptedParams)

Description copied from interface: HeaderFilter

Sets the names of the accepted header parameters.

Specified by:

setAcceptedParameters in interface HeaderFilter

Overrides:

setAcceptedParameters in class DefaultHeaderFilter

Parameters:

acceptedParams - The accepted header parameters. Must contain at least the alg parameter for JWS headers or the alg and enc parameters for JWE headers. Must not be null.
