FPM2 is GTK2 port from Figaro's Password Manager originally developed by John Conneely, with some new enhancements.

Upstream development seems to have stopped. It is therefore recommended to use a different password manager.

YAPET is a text based password manager using the Blowfish encryption algorithm. Because of its small footprint and very few library dependencies, it is suited for installing on desktop and server systems alike. The text based user interface allows you to run YAPET easily in a Secure Shell session. Two companion utilities enable users to convert CSV files to YAPET and vice versa.

This library is a C/C++ implementation of the zxcvbn password strength estimator. It provides functions to rate password strength, by comparing the password to several word lists, including English first and last names.

KeePass is a light-weight and easy-to-use password manager that helps you manage your passwords in a secure way. All passwords are stored in an encrypted database, which is locked with a master key or key file.

Shroud is a simple secret manager with a command line interface. The password database is stored as a Scheme s-expression and encrypted with a GnuPG key. Secrets consist of an arbitrary number of key/value pairs, making Shroud suitable for more than just password storage. For copying and pasting secrets into web browsers and other graphical applications, there is xclip integration.

Libpwquality is a library for password quality checking and generation of random passwords that pass the checks.

Makepasswd is a program that generates pseudo-random passwords of a desired length. It can also generate their corresponding hashes for a given encryption algorithm if so desired.

secretsd is a generic backend for the libsecret API to use on headless systems or minimal desktop environments. It stores secrets in a sqlite database, encrypted using a AES key. The database key is stored in a regular file next to the database by default, but can be read from an external program.

Hashcat is an password recovery utility, supporting five unique modes of attack for over 200 highly-optimized hashing algorithms. Hashcat currently supports CPUs, GPUs, and other hardware accelerators on Linux, Windows, and macOS, and has facilities to help enable distributed password cracking.

This is a cracker for openssl encrypted files. It can be used either in exhaustive mode to try every password given a charset or in dictionary mode to try every password contained in a file.

This package provides a secret service implementation for Himitsu, allowing seamless access for applications storing secrets through the protocol.

This package provides a git credential helper that queries Himitsu for credentials.

Passwdqc is a password/passphrase strength checking and policy enforcement toolset, including an optional PAM module, pam_passwdqc, command-line programs (pwqcheck, pwqfilter, and pwqgen), and a library, libpasswdqc.

pwclient is a VCS-agnostic tool for interacting with Patchwork, the web-based patch tracking system.

GNU Wdiff is a front-end to the diff program from Diffutils that allows you to compare files on a word-by-word basis, where a word is anything between whitespace.

E9Patch is a static binary rewriting tool for x86-64 ELF binaries, both executables and shared objects. The patched binaries can be used in place of the original, without requiring additional runtime dependencies. Binary patches can be defined through a high-level interface, which focuses on ease of use, or low-level interfaces, which provide additional flexibility and allow optimizations for performance.

Coccinelle is a tool that allows modification of C code using semantic patches in the SmPL for specifying desired matches and transformations in the C code.

Visual Binary Diff (vbindiff) displays files in hexadecimal and ASCII (or EBCDIC). It can also display two files at once, and highlight the differences between them. It works well with large files (up to 4 GiB).

Patchwork is a patch tracking system. It takes in emails containing patches, and displays the patches along with comments and state information. Users can login allowing them to change the state of patches.

Quilt allows you to easily manage large numbers of patches by keeping track of the changes each patch makes. Patches can be applied, un-applied, refreshed, and more.

wiggle attempts to apply patches to a target file even if the patches do not match perfectly.

Patchutils is a collection of programs that can manipulate patch files in useful ways such as interpolating between two pre-patches, combining two incremental patches, fixing line numbers in hand-edited patches, and simply listing the files modified by a patch.

Colordiff is Perl script wrapper on top of diff command which provides 'syntax highlighting' for various patch formats.

Meld is a visual diff and merge tool targeted at developers. Meld helps you compare files, directories, and version controlled projects. It provides two- and three-way comparison of both files and directories, and has support for many popular version control systems.

Meld helps you review code changes and understand patches. It might even help you to figure out what is going on in that merge you keep avoiding.
