На ИСе есть пару статей на эту тему, но, повторюсь, не для SHA-512.
Вот ссылки:
На одном из сайтов наткнулся на итнересную идею: использовать готовые функции на других скриптовых языках программирования и заставить их выполняться в 1С. Таким образом можно компенсировать в 1С отсутсвие побитовых операций, доступ к WMI и всего прочего. Сделать нам это поможет Microsoft Script Control.
Объект Microsoft Script Control позволит исполнить код на VBScript или JScript. Присутствует в Windows начиная с версии 2000, в более ранних может быть установлен.
Конечно, я не претендую на оригинальность идеи, но, все же я думаю, кто-то найдет эту информацию полезной для себя.
Таким макаром получилось очень быстро сделать функцию для работы с хэшем SHA-512. Вот, что получилось:
Функция SHA512(Стр)
ScrptCtrl = Новый COMОбъект("MSScriptControl.ScriptControl");
ScrptCtrl.Language = "JScript";

КонецФункции
Код функции на JScript взят с: http://www.happycode.info/javascript-sha-512/
Я думаю чуть-чуть модифицировав код, можно завставить шифровать и расшифровывать данные, добавить другие хэш-функции и т.д. Да и вообще использовать подобный подход в других направлениях.
PS: В комментариях к статье пользователь yukon предложил способ, который позволяет добиться того же, но испоьзуя другие возможности (требуется .Net):
Текст = Новый COMОбъект("System.Text.UTF8Encoding"); КриптоSHA512 = Новый COMОбъект("System.Security.Cryptography.SHA512Managed"); Хэш = КриптоSHA512.ComputeHash_2(Текст.GetBytes_4("ололо")).Выгрузить();
Этот код вернет массив из которого не сложно получить хэш строкой.
