Anyone is free to post a hash, along with a signature. Use of this site is at your own risk, and I provide no guarantees as to its stability or fitness for purpose. To use this site, create a document containing your idea, and append at least 74 random characters. Create a hash using SHA-2. Sign using GPG. Then upload both the hash and the signature. If at some later point you need to prove when you wrote the intial file, you can use the signed hash here, together with the upload time stamp, to prove a bound on when you wrote it. Simples! Why 74 random bits? Well, just for your own piece of mind. 74 ASCII characters take more than 512 bits to represent (518 to be exact). If they are chosen uniformly at random there is no way to compress that part of the document below 518 bits, which is longer than a SHA-2 hash. Thus there is no way you could have been tricked into uploading a compressed version of your document.

Its like you read my mind! You seem to know a lot about
this, like you wrote the book in it or something.
I think that you can do with a few pics to drive the message home a
little bit, but instead of that, this is fantastic blog.
An excellent read. I will certainly be back.

Конструктивная глубина предоставляет способность ставить её в некоторые панельные строения, заполняя практично ширину стены.
Выгодно то, что, делать монтаж откосов в таких домах не будет потребности.
Дверное полотно сконструировано из железного листа массивностью один с половиной мм. с элементами усиления. В паре с утеплителем из менералловаты и двумя теплыми накладками 16 мм её ширина составляет восемьдесят пять мм.
Эти составляющие отвечают высокому классу шумопоглащения и теплосбережения.
В обычную наборку ещё включены 3 завеса, импортных запорных устройства Kale (сувальдный и цилиндричечкий), 2 противосъёмных штыря , смотровое устройство и нижняя планка из нержавейки.
