Introduction
Laravel's encrypter uses OpenSSL to provide AES-256 and AES-128 encryption. You are strongly encouraged to use Laravel's built-in encryption facilities and not attempt to roll your own 'home grown' encryption algorithms. All of Laravel's encrypted values are signed using a message authentication code (MAC) so that their underlying value can not be modified once encrypted.
Jul 29, 2019 It is all about how OpenSSL does its formating and key generation. The ciphertext was actually changing, but the first part of it was staying the same. Let’s encrypt some plaintext with 256-bit CBC. We want to generate a 256-bit key and use Cipher Block Chaining (CBC). The basic command to use is openssl enc plus some options: -P — Print out the salt, key and IV used, then exit. We want to generate a 256-bit key and use Cipher Block Chaining (CBC).

Mar 12, 2020 Generating AES keys and password Use the OpenSSL command-line tool, which is included with InfoSphere® MDM, to generate AES 128-, 192-, or 256-bit keys. The madpwd3 utility is used to create the password. Laravel's encrypter uses OpenSSL to provide AES-256 and AES-128 encryption. You are strongly encouraged to use Laravel's built-in encryption facilities and not attempt to roll your own 'home grown' encryption algorithms. You should use the php artisan key:generate command to generate this key since this Artisan command will use PHP's secure.
Configuration
Before using Laravel's encrypter, you must set a
key
option in your config/app.php
configuration file. You should use the php artisan key:generate
command to generate this key since this Artisan command will use PHP's secure random bytes generator to build your key. If this value is not properly set, all values encrypted by Laravel will be insecure.![Openssl aes 256 key generation download Openssl aes 256 key generation download](/uploads/1/2/6/1/126140091/963461997.png)

You may encrypt a value using the
encrypt
helper. All encrypted values are encrypted using OpenSSL and the AES-256-CBC
cipher. Furthermore, all encrypted values are signed with a message authentication code (MAC) to detect any modifications to the encrypted string:Encrypting Without Serialization
