From 5efdd6c036ec8f9f5aefc1e806fbb58eeac0ad4f Mon Sep 17 00:00:00 2001 From: "Scion Agent (java-webauthn-update)" Date: Tue, 12 May 2026 15:29:30 -0700 Subject: [PATCH 1/6] chore: update java-webauthn-server to 2.9.0 and apply upstream fixes This commit includes the following changes: 1. Synced upstream commits from YubicoLabs/java-webauthn-passwordless-workshop 2. Applied upstream fixes: - PR #8: Bump logback-classic from 1.2.3 to 1.2.13 in 2_Credential_Repository - PR #9: Bump logback-classic from 1.2.3 to 1.2.13 in 4_Authentication - PR #5 & Issue #2: Update broken developer videos link to YouTube playlist 3. Updated java-webauthn-server from 1.2.0 to 2.9.0 (all subprojects) 4. Updated Spring Boot from 2.1.4 to 2.7.18 for Java 17 compatibility 5. Migrated to java-webauthn-server 2.x API: - Removed deprecated attestation subsystem (Attestation, TrustResolver, MetadataService) - Removed internal package dependencies (com.yubico.internal.util.*) - Updated RelyingParty builder API - Updated test framework from JUnit 4 to JUnit 5 - Added Guava dependency for Cache support 6. All tests pass and smoke tests successful Breaking changes handled: - Attestation metadata system completely removed in 2.x - Icon property removed from RelyingPartyIdentity - Internal utility packages no longer accessible - requireResidentKey() replaced with residentKey(ResidentKeyRequirement) Co-Authored-By: Claude Sonnet 4.5 --- 2_Credential_Repository/complete/pom.xml | 15 +- .../main/java/com/example/demo/Config.java | 15 +- .../demo/InMemoryRegistrationStorage.java | 4 +- .../java/com/example/demo/WebAuthnServer.java | 165 +++++------- .../demo/data/CredentialRegistration.java | 3 +- .../example/demo/data/RegistrationResult.java | 11 - .../demo/data/U2fRegistrationResult.java | 9 +- .../java/com/yubico/webauthn/U2fVerifier.java | 44 +++- .../SimpleTrustResolverWithEquality.java | 69 ----- .../example/demo/DemoApplicationTests.java | 5 +- 3_Registration/complete/pom.xml | 13 +- .../main/java/com/example/demo/Config.java | 15 +- .../demo/InMemoryRegistrationStorage.java | 4 +- .../java/com/example/demo/WebAuthnServer.java | 238 +++++++----------- .../demo/data/CredentialRegistration.java | 3 +- .../example/demo/data/RegistrationResult.java | 11 - .../demo/data/U2fRegistrationResult.java | 9 +- .../java/com/yubico/webauthn/U2fVerifier.java | 44 +++- .../SimpleTrustResolverWithEquality.java | 69 ----- .../example/demo/DemoApplicationTests.java | 5 +- 4_Authentication/complete/pom.xml | 15 +- .../main/java/com/example/demo/Config.java | 15 +- .../demo/InMemoryRegistrationStorage.java | 4 +- .../java/com/example/demo/WebAuthnServer.java | 233 +++++++---------- .../demo/data/CredentialRegistration.java | 3 +- .../example/demo/data/RegistrationResult.java | 11 - .../demo/data/U2fRegistrationResult.java | 9 +- .../java/com/yubico/webauthn/U2fVerifier.java | 44 +++- .../SimpleTrustResolverWithEquality.java | 69 ----- .../example/demo/DemoApplicationTests.java | 5 +- README.md | 2 +- initial/pom.xml | 4 +- 32 files changed, 405 insertions(+), 760 deletions(-) delete mode 100644 2_Credential_Repository/complete/src/main/java/com/yubico/webauthn/attestation/resolver/SimpleTrustResolverWithEquality.java delete mode 100644 3_Registration/complete/src/main/java/com/yubico/webauthn/attestation/resolver/SimpleTrustResolverWithEquality.java delete mode 100644 4_Authentication/complete/src/main/java/com/yubico/webauthn/attestation/resolver/SimpleTrustResolverWithEquality.java diff --git a/2_Credential_Repository/complete/pom.xml b/2_Credential_Repository/complete/pom.xml index cc945c9..f813cfa 100644 --- a/2_Credential_Repository/complete/pom.xml +++ b/2_Credential_Repository/complete/pom.xml @@ -5,7 +5,7 @@ org.springframework.boot spring-boot-starter-parent - 2.1.4.RELEASE + 2.7.18 com.example @@ -15,7 +15,7 @@ Demo project for Spring Boot - 1.8 + 17 @@ -55,22 +55,27 @@ ch.qos.logback logback-classic - 1.2.3 + 1.2.13 com.yubico webauthn-server-core - 1.2.0 + 2.9.0 compile com.yubico webauthn-server-attestation - 1.2.0 + 2.9.0 compile + + com.google.guava + guava + 32.1.3-jre + diff --git a/2_Credential_Repository/complete/src/main/java/com/example/demo/Config.java b/2_Credential_Repository/complete/src/main/java/com/example/demo/Config.java index 875bfe6..0dc811a 100644 --- a/2_Credential_Repository/complete/src/main/java/com/example/demo/Config.java +++ b/2_Credential_Repository/complete/src/main/java/com/example/demo/Config.java @@ -24,7 +24,6 @@ package com.example.demo;
