How to get cache images path

Question

I am showing Listrak on site recommend product on my website.

Product images are very big, I need resizes images.

I have images name like 2/0/20mm.jpg and I am appeding it with https://example.com/media/catalog/product

So it will be

https://example.com/media/catalog/product/2/0/20mm.jpg

But i want

https://example.com/media/catalog/product/cache/fc6ca0131474e1299ecedb80f5002264/2/0/20mm.jpg

Note: I do not have product object, So can't load an get resized images that why need to get cache folder path so I will append image name.

Thanks in advance!

You can hard code the hash as it depends only on the image target format and mostly does not change.
