Below, we will discuss why this error occurs and how to resolve it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Understanding the Error<\/h2>\n\n\n\n<p>In Laravel Passport, authentication relies on private and public keys stored in the <code>storage\/oauth-private.key<\/code> and <code>storage\/oauth-public.key<\/code> files. If these keys are missing, corrupted, or incorrectly set up, the application will throw the &#8220;Invalid key supplied&#8221; exception.<\/p>\n\n\n\n<p>The error occurs in the <code>CryptKey.php<\/code> file in the <code>league\/oauth2-server<\/code> package, which Laravel Passport depends on. Specifically, the exception is triggered when the system fails to validate the provided key:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>throw new LogicException('Invalid key supplied');<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Solution<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Generate New Keys<\/h3>\n\n\n\n<p>To resolve this issue, regenerate the Passport keys by running the following command in your terminal:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>php artisan passport:keys<\/code><\/pre>\n\n\n\n<p>This command will generate new private and public keys inside the <code>storage\/<\/code> directory, ensuring your authentication system works correctly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Force Regeneration of Keys<\/h3>\n\n\n\n<p>If the above command doesn\u2019t resolve the issue, you can force the regeneration of keys using:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>php artisan passport:keys --force<\/code><\/pre>\n\n\n\n<p>This ensures that the existing keys are replaced with new ones.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Verify File Permissions<\/h3>\n\n\n\n<p>Ensure that the <code>storage\/oauth-private.key<\/code> and <code>storage\/oauth-public.key<\/code> files have the correct permissions. On Linux\/macOS, you can set appropriate permissions using:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>chmod 600 storage\/oauth-private.key storage\/oauth-public.key<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">4. Clear Configuration Cache<\/h3>\n\n\n\n<p>After regenerating the keys, clear Laravel\u2019s configuration cache to ensure it loads the latest keys:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>php artisan config:clear\nphp artisan cache:clear<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">5. Restart the Server<\/h3>\n\n\n\n<p>If you are using Laravel&#8217;s built-in server, restart it:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>php artisan serve<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"<p>Introduction While working with Laravel Passport for authentication, you may encounter the following error: This error indicates that the OAuth key used for authentication is either missing&#8230; <\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1612],"tags":[2423,2079,931,671,2421,1091,42,2420,1292,533,826,2424,2425,35,2419,76,2422,2426,675],"class_list":["post-2993","post","type-post","status-publish","format-standard","hentry","category-laravel-tutorial","tag-access-token","tag-api-security","tag-artisan-commands","tag-authentication","tag-cryptkey","tag-debugging","tag-laravel","tag-laravel-api","tag-laravel-errors","tag-laravel-passport","tag-laravel-troubleshooting","tag-oauth","tag-passport","tag-php","tag-php-security","tag-private-key","tag-public-key","tag-token-authentication","tag-web-development"],"_links":{"self":[{"href":"https:\/\/www.devopssupport.in\/blog\/wp-json\/wp\/v2\/posts\/2993","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.devopssupport.in\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.devopssupport.in\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.devopssupport.in\/blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.devopssupport.in\/blog\/wp-json\/wp\/v2\/comments?post=2993"}],"version-history":[{"count":1,"href":"https:\/\/www.devopssupport.in\/blog\/wp-json\/wp\/v2\/posts\/2993\/revisions"}],"predecessor-version":[{"id":2995,"href":"https:\/\/www.devopssupport.in\/blog\/wp-json\/wp\/v2\/posts\/2993\/revisions\/2995"}],"wp:attachment":[{"href":"https:\/\/www.devopssupport.in\/blog\/wp-json\/wp\/v2\/media?parent=2993"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.devopssupport.in\/blog\/wp-json\/wp\/v2\/categories?post=2993"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.devopssupport.in\/blog\/wp-json\/wp\/v2\/tags?post=2993"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
