Generate Key Code

@Popnoodles Yes, and this answer was just pointing out other potential problems that might afflict the asker. Frankly, the quick fix was using a notepad editor at the time - but I didn't even know if OP was using Netbeans or not - it could have been any other IDE with a similar issue. Nov 30, 2016  An encryption key must also be configured. Typically this is done by running the following artisan command: php artisan key:generate The key:generate command will update the application's environment file with the key that is generated during command execution. Encryption keys must be a random, thirty-two character long string.

Laravel Key Too Long

Encryption is a process of converting a plain text to a message using some algorithms such that any third user cannot read the information. This is helpful for transmitting sensitive information because there are fewer chances for an intruder to target the information transferred.

Encryption is performed using a process called Cryptography. The text which is to be encrypted is termed as Plain Text and the text or the message obtained after the encryption is called Cipher Text. The process of converting cipher text to plain text is called Decryption.

Laravel uses AES-256 and AES-128 encrypter, which uses Open SSL for encryption. All the values included in Laravel are signed using the protocol Message Authentication Code so that the underlying value cannot be tampered with once it is encrypted.

Configuration

Generate authorized key with ssh-keygen. The command used to generate the key in Laravel is shown below −

Please note that this command uses the PHP secure random bytes’ generator and you can see the output as shown in the screenshot given below −

The command given above helps in generating the key which can be used in web application. Observe the screenshot shown below −

Note

The values for encryption are properly aligned in the config/app.php file, which includes two parameters for encryption namely key and cipher. If the value using this key is not properly aligned, all the values encrypted in Laravel will be insecure.

Encryption Process

Encryption of a value can be done by using the encrypt helper in the controllers of Laravel class. These values are encrypted using OpenSSL and AES-256 cipher. All the encrypted values are signed with Message Authentication code (MAC) to check for any modifications of the encrypted string.

The code shown below is mentioned in a controller and is used to store a secret or a sensitive message.

Decryption Process

Decryption of the values is done with the decrypt helper. Observe the following lines of code −

Please note that if the process of decryption is not successful because of invalid MAC being used, then an appropriate exception is thrown.
