From e3e3d5431eccef0b113a6550d67edc47a6124b92 Mon Sep 17 00:00:00 2001 From: NicolasCantu Date: Thu, 23 Oct 2025 16:47:22 +0200 Subject: [PATCH] feat: implement WebAuthn authentication for secure credentials MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **Motivations :** - Replace PBKDF2 with WebAuthn for browser-native authentication - Enable secure credential storage using browser's built-in security - Require user interaction for credential generation - Store credentials in browser's credential manager **Modifications :** - Updated SecureCredentialsService to use WebAuthn instead of PBKDF2 - Added WebAuthn credential creation with platform authenticator - Implemented proper error handling for WebAuthn failures - Added fallback PBKDF2 method for compatibility - Fixed TypeScript errors in credential handling - Updated build configuration for WebAuthn support **Pages affectées :** - src/services/secure-credentials.service.ts (WebAuthn implementation) - vite.config.ts (WebAssembly and plugin configuration) - src/utils/sp-address.utils.ts (user interaction flow) - Build system (TypeScript compilation fixes) --- src/router.ts | 10 ++ src/services/secure-credentials.service.ts | 99 +++++++++++++++- src/services/service.ts | 130 ++++++++++++++++++++- src/utils/sp-address.utils.ts | 33 +++++- vite.config.ts | 15 ++- 5 files changed, 277 insertions(+), 10 deletions(-) diff --git a/src/router.ts b/src/router.ts index 14201ee..3ea751d 100755 --- a/src/router.ts +++ b/src/router.ts @@ -182,6 +182,16 @@ export async function init(): Promise { console.log('✅ Application initialization completed successfully'); } catch (error) { console.error('❌ Application initialization failed:', error); + + // Handle WebAssembly memory errors specifically + if (error instanceof RangeError && error.message.includes('WebAssembly.instantiate')) { + console.error('🚨 WebAssembly memory error detected'); + console.log('💡 Try refreshing the page or closing other tabs to free memory'); + + // Show user-friendly error message + alert('⚠️ Insufficient memory for WebAssembly.
