The cryptographic algorithms known as ‘hash’ can make a huge difference to your data security. MD5 and SHA-1 are the most used cryptographic algorithms used to compare two pieces of stand-alone content in the PC world. A good hash algorithm has several characteristics, including: It will output the same hash result for the same exact input, every time. Microsoft made a formal announcement during the Windows Vista beta program to begin removing all instances of MD-5 and Sha-1 from Windows. The increase in bit size theoretically makes the collisions more difficult to generate.”]
