Hash-256 Information

The electronic fingerprint is a hash code, obtained using the universal cryptography SHA256 algorithm created by the "United States National Security Agency (NSA / CSS)". The collision probability, i.e. the HASH code resulting from applying, the SHA256 algorithm to two different files, is equal, is about 1 in 10 18 . However, the likelihood that the resulting SHA256 hash algorithm applying, the same document repeatedly, it is different from zero. This means that there has not been manipulation.
