1, Use a GUID generator

GUID( Globally unique identifier ) is a 32-bit hexadecimal string which was promised to be an absolutely unique number, such as 602ebc7c-080e-4d9b-a06b-1ce92def1e0a, and there are plenty of online GUID generators.

2, Use a MD5 hash generator

Using your birth date or mobile number as a password is silly, for instance, 19880123 is too plain and too simple , but if you create a MD5 hash of 19880123, you will get a very complicated string: 98bf51669e7a5552403f3f15f59788c2.

3, Use a SHA1 hash generator

How about a password like 8d969eef6ecad3c29a3a629280e686cf0c3f5d5a86aff3ca12020c923adc6c92? Actually it’s the SHA-1 hash checksum value of the string “123456″.

4, Use a Random Password Generator

Yesterday we covered an excellent random password generator – Wireless Key Generator, it is an easy using and powerful utility for creating strong password.

5, Use an Old-School Tabula Recta
