A portable password manager application written in Java.

It stores your passwords in an encrypted file that you can keep on removable media.

How to build it

To build the project you will need:

• Maven
• Java JDK 1.8
• An Internet connection for downloading dependencies

Assuming you have all of these, issue this command from the project root directory:

mvn package

The built application packages will be created in the target directory.

How to install it

Take the built package of your choice (packages are built in Zip, TAR/GZ and TAR/BZ2 formats) and extract it into an installation directory. This can be on removable media, such as a USB memory stick.

How to use it

Run the KeyRing.bat batch file or KeyRing shell script depending on which OS you are using. Basic usage is printed to the console.

To store a password for a user called "Bill" on a web site called "www.foo.com":

KeyRing put www.foo.com Bill

To see the stored password for the user on the site:

KeyRing get www.foo.com Bill

Cryptography Notes

All passwords are encrypted using

• 256-bit AES
• The encryption key is derived from the user supplied password using the scheme in PKCS12
• The password is salted with cryptographically random salt
• Cryptographic functions are used from the Bouncy Castle cryptographic library
