Oct 04, 2018 Elliptic Curve Cryptography, or ECC, is a powerful approach to cryptography and an alternative method from the well known RSA. It is an approach used for public key encryption by utilizing the mathematics behind elliptic curves in order to generate security between key pairs. Elliptical curve cryptography (ECC) is a public key encryption technique based on elliptic curve theory that can be used to create faster, smaller, and more efficient cryptographic keys.
Definition
Provides an abstract base class that encapsulates the Elliptic Curve Digital Signature Algorithm (ECDSA).
- Derived
Remarks
This class serves as the abstract base class for ECDsaCng derivations.
Aug 24, 2017 Running php artisan key:generate in a Laravel project where the.env file does not contain an APPKEY= line results in the following output: Application key base64:KEYHERE= set successfully. However, the key is not written to the.env file, so the status message is incorrect. Steps To Reproduce: Create a.env file without an APPKEY= line. Dec 07, 2016 php artisan key:generate Regenerating the Application Key It is important to note that if the encryption key needs to be regenerated after an application has been in use, any data that was previously encrypted using the old key cannot be decrypted using the new encryption key. Php artisan key generate reset.
