Random number and password generation

Java classes for random number generation:

• password,
• key,
• md5,

Password generation is not so easy. There are two common errors with random password generation:

• generated password is inelegant word, for example: "1something2"
• generated password containst problematic charactes, for example: "1" and "l" or "O" and "0"

Usage

// create new password for sms or email sending (about 1e5 combination)
String password = new PasswordGenerator().generate();

// create new password (about 1e10 combination)
String strongPassword = new StrongPasswordGenerator().generate()

// create statistically unique key (about 2e39 combination) - 22 chars safly for URLs
String key = new KeyGenerator().generate();

// create random hex encoded MD5 (2^128 combination) - 32 chars
String md5 = new Md5HexGenerator().generate();
