How to add encryption key in sha256 algorithm in php?

@deron 

To add an encryption key in the SHA256 algorithm in PHP, you can use the hash_hmac() function. Here's an example:

1
2
3
4
5
6

$key = 'your-encryption-key';
$data = 'data-to-be-encrypted';

$encryptedData = hash_hmac('sha256', $data, $key);

echo $encryptedData;

In this example, $key is the encryption key you want to use, and $data is the data you want to encrypt. The hash_hmac() function will generate an HMAC using the SHA256 algorithm with the provided key and data. The resulting encrypted data will be stored in the $encryptedData variable.

You can replace 'your-encryption-key' with your actual encryption key and 'data-to-be-encrypted' with your actual data to get the desired result.
