Examples

A 40-bit WEP key:

KeePass::Password.generate('h{10}')
#=> "ae6929dc0e"

A random MAC address:

KeePass::Password.generate('HH\-HH\-HH\-HH\-HH\-HH', :permute => false)
#=> "0D-4D-32-64-EB-7D"

A password with 10 alphanumeric characters, where at least 2 are upper case and at least are 2 lower case characters:

KeePass::Password.generate('uullA{6}')
#=> "us2j1nTIQT"

A password with 20 alphanumeric and symbol characters, without any lookalike characters (e.g., I and |):

KeePass::Password.generate('[As]{20}', :remove_lookalikes => true)
#=> "-2~[+Rze{hZezk(\\nZ-W"

Invalid patterns raise an exception:

KeePass::Password.generate('[\I\|]{3}', :remove_lookalikes => true)
#=> KeePass::Password::InvalidPatternError: empty character set for token 1 for "[\\I\\|]{3}"
