Imagick::encipherImage function in PHP is used to encipher an image using a secret passphrase. This function is mainly used for encrypting an image to ensure data security.

Here is an example of how to use the Imagick::encipherImage function:

php
<?php
// Create a new Imagick object
$image = new Imagick('input.jpg');

// Set the passphrase
$passphrase = 'secret';

// Encipher the image
$image->encipherImage($passphrase);

// Save the enciphered image
$image->writeImage('output.jpg');
?>


In the above example, we first create a new Imagick object using the input image 'input.jpg'. Then, we set the passphrase to 'secret'. Finally, we call the encipherImage function on the image object to encrypt the image using the passphrase, and save the enciphered image as 'output.jpg'.

Note that this function requires the Imagick extension to be installed and enabled in PHP.
