How to calculate hash MD5-SHA1-SHA-256-CRC32 in Windows Linux Mac and online

What they are  Hash are used in computer science to map a string (a sequence of bits) of arbitrary length into a string of predefined length.  It is a sort of ‘signature’ of an electronic document. For each string you can calculate a hash, so each different string will have different hashes.  However, calculating the

Phishing brought to extreme levels exploiting punycode – How it works, how it to prevent and be sure of websites through SSL

Punycode is an encoding system that serves to represent a sequence of unicode characters via an ASCII character sequence, to make it possible to use these sequences in domain names, without having to modify existing infrastructure and standards.  In this way you can manage internationalized domain names (IDNA) by adding the characters ‘xn–‘ to the beginning of the punycode string.  For example, by entering xn–google.com as address, we

Public IP address and DDNS: what it is, how to check and set it to reach devices in LAN from WAN

A computer or any device, when connected to a network (LAN), is identified by an IP address assigned by the router.  This address is usually in the form 192.168.X.Y and it is released by the router’s DHCP to identify the various devices connected to it.   However, since the router itself is connected to the Internet
