Method Details

getEval

public Optional<Extensions.Prf.PrfValues> getEval()

PRF inputs to use for any credential without a dedicated input listed in getEvalByCredential().

Since:

2.7.0

See Also:

• eval(PrfValues)
• evalByCredentialWithFallback(Map, PrfValues)
• AuthenticationExtensionsPRFInputs.eval
• §10.1.4. Pseudo-random function extension (prf)

getEvalByCredential

public Optional<Map<ByteArray,Extensions.Prf.PrfValues>> getEvalByCredential()

A map of credential IDs to PRF inputs to use for that credential. Credentials without a mapping here fall back to the inputs in getEval() if present, otherwise no PRF is evaluated for those credentials.

Since:

2.7.0

See Also:

• evalByCredential(Map)
• evalByCredentialWithFallback(Map, PrfValues)
• AuthenticationExtensionsPRFInputs.evalByCredential
• §10.1.4. Pseudo-random function extension (prf)

eval

public static Extensions.Prf.PrfAuthenticationInput eval(@NonNull
 @NonNull Extensions.Prf.PrfValues eval)

Use the same PRF inputs for all credentials.

Since:

2.7.0

See Also:

• getEval()
• AuthenticationExtensionsPRFInputs.eval
• §10.1.4. Pseudo-random function extension (prf)

evalByCredential

public static Extensions.Prf.PrfAuthenticationInput evalByCredential(@NonNull
 @NonNull Map<PublicKeyCredentialDescriptor,Extensions.Prf.PrfValues> evalByCredential)

Use different PRF inputs for different credentials, and skip PRF evaluation for any credentials not present in the map.

Since:

2.7.0

See Also:

• getEvalByCredential()
• AuthenticationExtensionsPRFInputs.evalByCredential
• §10.1.4. Pseudo-random function extension (prf)

evalByCredentialWithFallback

public static Extensions.Prf.PrfAuthenticationInput evalByCredentialWithFallback(@NonNull
 @NonNull Map<PublicKeyCredentialDescriptor,Extensions.Prf.PrfValues> evalByCredential,
 @NonNull
 @NonNull Extensions.Prf.PrfValues eval)

Use different PRF inputs for different credentials, and "fallback" inputs for any credentials not present in the map.

Parameters:

evalByCredential - a map of credential IDs to PRF inputs to use for that credential.

eval - "fallback" inputs to use for any credential not listed in evalByCredential.

Since:

2.7.0
