PWGen can generate strong passwords using random character sequences as well as secure passphrases composed of multiple words from a default list with over 8000 entries. You can also combine words with characters and so increase the security even more.
One can set the number of characters and/or words to be used, choose a character set from those pre-loaded and generate a list with multiple passwords that can be automatically saved to any specified location.
Other options allow you to include special symbols, upper-case and lower-case letters, convert the entire word list to lower-case and customize the length of words used in passphrases. Additionally, PWGen features clipboard encryption and random data files creation.
