  PassTrust Password Generator

    Usage: passtrust [options]
    -v, --verify                     Ask the keyword twice
    -l, --length [LENGTH]            Change password length (default is 16, max is 64)
    -t, --timeout [SECONDS]          Change the amount of seconds the password will be on screen (default is 10)
    -c, --clipboard                  Copy the password to the clipboard
    -s, --secret                     Don't show any character when typing
    -r, --random                     Don't ask for a passphrase, use a random one.
    -h, --help                       Show this message

To use the default options, run passtrust without arguments.

$ passtrust
Password will be 16 characters long
Enter passphrase:

To make passtrust ask the passphrase twice (useful if you don't want to risk mistyping and losing your password in the future)

$ passtrust -v
Password will be 16 characters long
Verification is on
Enter passphrase: 

The default timeout is 10 seconds, this can be changed with the -t flag

$ passtrust -t 30
Password will be 16 characters long
Enter passphrase: [something]
Your generated password is: [something] 
The screen will clear in 30 seconds.

The password length can be changed with -l, maximum is 64 and minimum is 16.

$ passtrust -l 32
Password will be 32 characters long
Enter passphrase:

As you type in your password, the characters will show up as * . You can disable that with the -s flag

$ passtrust -s
Password will be 16 characters long
Secret mode is activated
Enter passphrase: 

If you have the clipboard gem installed, you can use the clipboard options. When you pass the -c flag, the generated password will be copied to your clipboard. It will then be replaced with a fake one when the timer reaches zero.

$ passtrust -c
Password will be 16 characters long
Enter passphrase: [something]
Your generated password is: [something]
Password has been copied to your clipboard.
Text in clipboard will be replaced with a fake after timer.
The screen will clear in 10 seconds.

If you don't want to think of a passphrase, passtrust can generate a random passphrase as well.

$ passtrust -r
Password will be 16 characters long
Your random passphrase is: 
"[something]"
Your generated password is: [something]
The screen will clear in 10 seconds.
