Method Detail

getKeychain

public Keychain getKeychain()

getSkew

public long getSkew()

Specified by:

getSkew in interface Verifier

Returns:

server skew in milliseconds

setSkew

public void setSkew(long skew)

Deprecated. will remove to make the class immutable. use constructor overload instead.

Parameters:

skew - new server skew in milliseconds

selectKey

public Key selectKey(Authorization authorization)

Selects an appropriate Key from the Keychain matching the keyId specified in the Authorization. This method is called by Verifier.verifyWithResult(Challenge, RequestContent, Authorization), but can be called by client code to retrieve the identified Key directly

selectKey in interface Verifier

Parameters:

authorization - the Authorization header

Returns:

a matching Key or null

verify

verify in interface Verifier

Parameters:

challenge - the WWW-Authenticate challenge sent to the client in the previous response

requestContent - the RequestContent containing the request header content

authorization - the Authorization header to verify

Returns:

true if valid (VerifyResult.SUCCESS), false otherwise

verifyWithResult

public VerifyResult verifyWithResult(Challenge challenge,
                                     RequestContent requestContent,
                                     Authorization authorization)
