Default Generator

Unless otherwise specified in your config/etags.php, the GenericGenerator is the default used etag Generator. Its main purpose is to hash arbitrary content, and create Etag instances with the hash value.

Depending on your configuration, two different hashing algorithms are used:

• weak_algo: used for when creating etags flagged as "weak" (e.g. for weak comparison)
• strong_algo: used for when creating etags that are NOT flagged as "weak" (e.g. for strong comparison)

return [
    // ...previous not shown ...

    'profiles' => [

        'default' => [
            'driver' => \Aedart\ETags\Generators\GenericGenerator::class,
            'options' => [
                'weak_algo' => 'crc32',
                'strong_algo' => 'sha1',
            ],
        ],
    ]
];

Feel free to specify whatever hashing algorithms your prefer, in the configuration. Furthermore, you are encouraged to review the source code of \Aedart\ETags\Generators\GenericGenerator to gain a better understanding of the generator works.
