1 개요

The only supported ciphers are AES-128-CBC and AES-256-CBC with the correct key lengths.

• 구버전에서는 비교적 짧은 키를 썼는데 버전이 올라가면서 더 긴 키를 사용한다..

3 조치방법

• 앱 키를 재생성하고, 설정 캐시를 클리어하자.

php artisan key:generate
php artisan config:clear

4 #jmnote

• 조치 전에, .env 파일이 제대로 있는지, 그 파일의 내용 중에 APP_KEY가 적절히 작성되어 있는지를 먼저 확인하자.
