A simple Password Generator
There are many big and complex Password generator scripts available on the Internet, but often we don’t need to go into such complexities.
Here is a simple one-line password generator code in PHP,
First, a random number is taken, then the MD5 hashing is done on it, then a substring is taken from that. That substring is your generated password.
In the above code just change the the last number (which is ‘8′ here), to get your desired length of password.
However this has two small limitations:
- Though the generated password will be alpha-numeric, the characters will not go beyond ‘F’ , since they are hex codes.
- Password length cannot be more than 32 characters, since a MD5 hash is taken. However you can always concatenate this code one after another to get any desired length of random password.
Anyway, these are very simple limitations, this will not bother you in ordinary cases.
Some examples of generated password are:
861cf
3ed0d10f
33dc56970486a86b15cc
