The OATH Toolkit makes it easy to build one-time password authentication systems. It contains shared libraries, commandline tools, and a PAM module. Supported technologies include the event-based HOTP algorithm (RFC4226) and the time-based TOTP algorithm (RFC6238). OATH stands for Open AuTHentication, which is the organization which specifies the algorithms. For managing secret key files, the Portable Symmetric Key Container (PSKC) format described in RFC6030 is supported.
KeePass is a light-weight and easy-to-use password manager that removes the need for you to remember many different passwords and makes it more feasible to use different passwords for each account. It manages your passwords in a secure database encrypted with AES and Twofish, which is locked with one master key or a key file.
Jumblar is a tool that converts map coordinates into passwords. It hopes to provide increased user security by assuming that it is easier for people to remember a secret location than a strong password, and that a location that could be anywhere in the world is practically impossible for others to guess. By using this property of secret locations, secure passwords can be generated. SCrypt is used to protect user information.
file2password is a utility that allows you to select a file (picture, document, music, etc.) and generate a secure password based on it. This means that there is no need to remember any password - just a picture or a filename. It is small (2 KB plus CSS), highly secure as it does not upload or shows the file used, supports drag and drop, can use online storage, and requires no server-side scripting.
Universal Password Manager (UPM) allows you to store usernames, passwords, URLs, etc. in an encrypted database protected by one master password. Its three strongest features are simplicity (it provides a small number of very strong features with no clutter), the ability to run cross-platform, and database sharing. Rather than having many separate databases (home, work, etc.), database sharing allows you store your database at a remote location (password protected HTTP URL, for example) and then have UPM automatically keep your local database in sync with the remote database.
CryptSharp provides a number of password crypt algorithms: BCrypt, MD5 (and Apache's htpasswd variant), PHPass (WordPress, phpBB, Drupal), SHA256, SHA512, and Traditional and Extended DES. It also includes Blowfish, SCrypt, and PBKDF2 for any HMAC (.NET's built-in PBKDF2 implementation supports only SHA-1). If you are looking to store passwords, odds are CryptSharp will have the algorithm you want.
SSAM (Spyshakers Account Manager) is a script that manages and protects online accounts. Passwords are encrypted and stored in a MySQL database. The encryption keys are not stored. Multiple accounts can be created under one installation. Folders of passwords can be pushed between accounts on the system. Security tools are built in to help protect accounts from spyware, key loggers, and screen capture devices. SSAM is perfect for Web masters and small businesses who need to manage their online accounts and keep them organized between founders, co-workers, or outsourced help.
