What Is Feisty Pass?
Feisty Pass is a password management app that automatically encrypts its entries by using feistel networks and another password.
-
How do I use Feisty Pass?
Feisty Pass is meant to offer some protect for sensitive information that you need to have available. It is not fool-proof security/encryption, but it should be enough for daily use.
Getting Started- Create your entries. It is recommended that you use two or more passwords to encrypt all your entries, one password for more important things, and another for less important things.
- Don't forget to include information in the encrypted section that may be needed, such as what email address was used or the username on an account.
-
Creating a New Entry
-
Press the "New" button at the bottom of the List screen.
This will display the form used to create new entries.
If the "New" button is not shown on the screen, taping the screen should make it appear. -
Fill out the form that appears.
The only requirement for the form is that the two password fields match. -
Press "Save".
This should create a new entry and display it for you.
-
Press the "New" button at the bottom of the List screen.
-
Editing an Entry
You can edit an entry even if it is encrypted. But if it is encrypted, you can only see and edit the title and description.
- From the List screen, Click on the entry you want to edit. This will display the specific entry.
- Optional: Decrypt the entry before editing it so that the password and encrypted content can be edited. Press the "Decrypt" button on the bottom of the screen and enter the correct password for this entry into the popup.
- From the Entry's Display screen, press the "Edit" button at the bottom of the screen. This will bring you to the edit screen for the specific entry.
-
In the edit screen, change the entry to your liking, then press "Save".
The only requirement for the form is that the two password fields match. If you leave the password fields blank, the entry's password will not change.
-
Fiesty Markup
Entries support markup in their description and in the encrypted section.
Password Box: This is a box meant to hold passwords, for a bit of added protection.
Form Input Entry Display -
Sorting Entries
From the List screen, make sure the "Sortable" checkbox at the end of the screen, then drag and drop the entries into place.
If the checkbox is not shown on the screen, taping the screen should make it appear. -
Encrypting Entries
On the specific entry's display page, press the "Encrypt" button. The entry should now be encrypted
Note: This button only appears on Decrypted entries, and is replaced with the "Decrypt" button on Encrypted entries. -
Decrypting Entries
On the specific entry's display page, press the "Decrypt" Button and enter the correct password.
If the password is incorrect, the page remains unchanged. If the password is correct, the encrypted section is decrypted
Note: This button only appears on Encrypted entries, and is replaced with the "Encrypt" button on decrypted entries.
You can also change the salt you're using to decrypt the entry with by clicking "salt" and changing the line that appears below. -
Deleting Entries
Deleting Individual Entries:
To delete a specific entry, starting from the List screen, Click on the entry you want to delete.
In the Entry's display screen, press the "Delete" button at the bottom of the screen.
Press the "Delete" button in the resulting Popup dialog to confirm deletion.
Deleting All Entries:
Go to the Options page at the top right corner of the screen.
The last option in the options page is "Delete All Entries", press it and press "Delete" on the resulting popup. -
Save to File
On the Options page, press the "Save to File" button. This will save a file to "Feisty/feistypass.txt" on your device.
It is hoped that a file dialog that lets you navigate and choose where to save this file can be implemented some day. -
Load from File
On the Options page, press the "Load from File" button. This will load a file from "Feisty/feistypass.txt" on your device.
It is hoped that a file dialog that lets you navigate and choose what file to load can be implemented some day.
Warning: This will erase all existing entries and replace them with the ones from the file. -
Salt
In Cryptography, a salt is random data that is used with a one-way function* on a password. By using this random data with a one-way function, it helps protect passwords from common types of attack such as "dictionary attacks" and pre-computed "rainbow table" attacks.
To change this app's salt, go to the Options page and edit the line of text with the "Salt" label to the top left of it. Changes are automatically saved and applied.
You can also use the "Generate Random Salt" button to generate a new random salt.
Warning: changing the salt will make any entry created with the previous salt harder to decrypt, requiring you to enter the old salt along with the password. This can be fixed by "changing" the password while the new salt is set, even if you're setting the password to it's current value.
* A one way function is something that takes input, and will produce an output based on that input, but which there is no function that can change that output back into the input. -
Encrypt on Edit
This Option controls whether the entry is encrypted upon editing it and before displaying it again, or keeps decrypted entries decrypted once an edit is saved.
If Encrypt on Edit is checked, then a decrypted entry will be encrypted when edits to it are saved.
If Encrypt on Edit is not checked, then a decrypted entry will remain decrypted when edits to it are saved. -
Encrypt on New
This Option controls whether the entry is encrypted upon creating it and before displaying it again, or keeps new entries decrypted once created.
If Encrypt on New is checked, then a new entry will be encrypted when created and displayed for the first time.
If Encrypt on New is not checked, then a new entry will remain decrypted when created and displayed for the first time. -
Generate Random Password
This Option effects entry creation.
If Generate Random Password is checked, then the form for creating a new entry will contain a randomly generated password in the secret section.
If Generate Random Password is not checked, then the form for creating a new entry will be entirely blank.
Randomly generated passwords consist of numbers, capital and lower case letters, and the following two symbols: -_
It is hoped password generation for this app can be improved in the future, but I have no idea of how to proceed on that. -
What is Cryptography
Cryptography is a collection of techniques for securely communicating with others despite the presence of observers. To Encrypt is to take a message and change it in such a way that it can no longer be read, but can still be decrypted. To Decrypt is to transform an encrypted message into a readable message.

What is a Bad Password
A bad password is one that is easy to guess or find out. Attackers try to guess passwords in a variety of ways, including trying common words and commonly used passwords. For these and other reasons, never use a password that is any of the following:
- 123456, 111111, 123123, or any predictable series of numbers.
- password - This one's especially bad, but any plain word is a problem.
- password1 - Also common, also bad because of that.
- qwerty
- abc123
- adobe123 - The name of the product you're using isn't going to protect you.
- admin - This is actually the default password for some devices.
- letmein
- Don't use the same word as your log-in, or any variation of it.
- Don't use only letters or only numbers.
- Don't use names of spouses, children, girlfriends/boyfriends or pets.
- Don't use phone numbers, Social Security numbers or birthdates.
- Don't use any word that can be found in the dictionary
-
What is a Feistel Network?
A Feistel Network is a key element of many encryption schemes, including Feisty Pass's. The steps a Feistel Network performs are as follows:
- Break the text into a left block (Ln) and a right block (Rn).
- Copy the right block into the new left block.
Ln+1 = Rn - Run the old right block and a key through a one way function*.
x = F(Rn, Kn) - Combine the previous result with the old left block to create the new right block.
Rn+1 = Ln ⊕ x - Repeat steps 1 through 4 for as many times as specified.
This process can be used to encrypt and decrypt a block of text.
