Interface SignatureCounter

All Known Implementing Classes:

GlobalSignatureCounter, NoSignatureCounter, PerCredentialSignatureCounter

public interface SignatureCounter

An interface that allows authenticators to keep track of the number of signatures they have performed.

This is done via a decoupled interface to enable authenticator implementations to support multiple styles of signature counting without implementing the logic for all of them at the same time.

Method Summary

Modifier and Type	Method and Description
int	increment(com.yubico.webauthn.data.ByteArray credentialId) Increment the signature count associated with the given credential ID.
int	initialize(com.yubico.webauthn.data.ByteArray credentialId) Initialize the signature count for a given credential ID.

Method Detail

increment

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

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.

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

Parameters:

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

Returns:

the new signature count.

initialize

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

Initialize the signature count for a given credential ID.

What Initialization entails exactly is implementation-defined.

Parameters:

credentialId - The credential ID.

Returns:

the initial signature count for the credential ID.
