de.adesso.softauthn.counter.NoSignatureCounter

All Implemented Interfaces:

SignatureCounter

public class NoSignatureCounter
extends java.lang.Object
implements SignatureCounter

A signature counter implementation that always returns 0 and effectively does nothing. This is the behaviour that should be employed by authenticators that don't support signature counting.

Method Detail

increment

public int increment(com.yubico.webauthn.data.ByteArray credentialId)

Description copied from interface: SignatureCounter

Increment the signature count associated with the given credential ID.

Note: This does not imply that there must be a one-to-one mapping between credential IDs and signature counts.

SignatureCounter.initialize(ByteArray) must have been called for the given credential ID before invoking this method for the first time.

Specified by:

increment in interface SignatureCounter

Parameters:

credentialId - The credential ID that was just used to sign something.

Returns:

the new signature count.

initialize

public int initialize(com.yubico.webauthn.data.ByteArray credentialId)

Description copied from interface: SignatureCounter

Initialize the signature count for a given credential ID.

What Initialization entails exactly is implementation-defined.

Specified by:

initialize in interface SignatureCounter

Parameters:

credentialId - The credential ID.

Returns:

the initial signature count for the credential ID.
