What is the format of the string, how is it encoded?

The service for checking individuals fssprus.ru returns a captcha image, which is dynamically loaded in the text received at the request of the server jquery function with a string in an incomprehensible encoding, I suspect that this is a picture that needs to be entered but I don’t understand how it is encoded, Tell me how to get a picture, half of the text I had to delete
the url with the answer
here is.fssprus.ru/ajax_search?callback=jQuery111301572...

It looks like the result of obfuscation through jsfuck or something like that.
In general, all this data is simply evalized in the end - here fssprus.ru/media/fssp2/decor/is/nscript.js?20170512 on line 148.
