FSearch is a fast file search utility, inspired by Everything Search Engine. It is written in C and based on GTK3.

Recoll finds documents based on their contents as well as their file names. It can search most document formats, but you may need external applications for text extraction. It can reach any storage place: files, archive members, email attachments, transparently handling decompression.

mlocate is a locate/updatedb implementation. The m stands for "merging": updatedb reuses the existing database to avoid rereading most of the file system, which makes it faster and does not trash the system caches as much. The locate(1) utility is intended to be completely compatible with slocate, and attempts to be compatible to GNU locate when it does not conflict with slocate compatibility.

Omega is a search application built on Xapian. It provides indexers and a CGI web search frontend.

GNU Bool is a utility to perform text searches on files using Boolean expressions. For example, a search for "hello AND world" would return a file containing the phrase "Hello, world!". It supports both AND and OR statements, as well as the NEAR statement to search for the occurrence of words in close proximity to each other. It handles context gracefully, accounting for new lines and paragraph changes. It also has robust support for parsing HTML files.

Hyper Estraier can be used to integrate full-text search into applications, using either the provided command line and CGI interfaces, or a C API.

Python library and command line tool for configuring a YubiKey. Note that after installing this package, you might still need to add appropriate udev rules to your system configuration to be able to configure the YubiKey as an unprivileged user.

This package provides a module implementing PAM over U2F, providing an easy way to integrate the YubiKey (or other U2F compliant authenticators) into your existing infrastructure.

SoftHSM 2 is a software implementation of a generic cryptographic device with a PKCS #11 Cryptographic Token Interface.

This package provides the pcsc_scan, ATR_analysis, scriptor, and gscriptor commands, which are useful tools to test a PC/SC driver, card or reader or send commands in a friendly environment (text or graphical user interface).

The pyscard smart card library is a framework for building smart card aware applications in Python. The smart card module is built on top of the PCSC API Python wrapper module.

The Belgian eID middleware is required to authenticate with online services and sign digital documents with Belgian identity cards.

It requires a running pcscd service and a compatible card reader.

This package provides a PC/SC IFD handler implementation for devices compliant with the CCID and ICCD protocols. It supports a wide range of readers and is needed to communicate with such devices through the pcscd resource manager.

libfido2 provides library functionality and command-line tools to communicate with a FIDO device over USB, and to verify attestation and assertion signatures.

libfido2 supports the FIDO U2F (CTAP 1) and FIDO 2.0 (CTAP 2) protocols.

The Yubico PIV tool is used for interacting with the Privilege and Identification Card (PIV) application on a YubiKey. With it you may generate keys on the device, import keys and certificates, create certificate requests, and other operations. It includes a library and a command-line tool.

The YubiKey Personalization package contains a C library and command line tools for personalizing YubiKeys. You can use these to set an AES key, retrieve a YubiKey's serial number, and so forth.

OpenSC is a set of software tools and libraries to work with smart cards, with the focus on smart cards with cryptographic capabilities. OpenSC facilitate the use of smart cards in security applications such as authentication, encryption and digital signatures. OpenSC implements the PKCS #15 standard and the PKCS #11 API.

DFU tool for updating Nitrokey token firmware.

nitrocli is a program that provides a command line interface for interaction with Nitrokey Pro, Nitrokey Storage, and Librem Key devices.

This package provides library to encode/decode base64, base64url, base32, base32hex and hex.

This application is developed and issued by the German government to be used for online authentication with electronic German ID cards and residence titles. To use this app, a supported RFID card reader or NFC-enabled smart phone and a running pcscd service are required.

Yubikey-oath-demenu lets you pick an OATH credential from your YubiKey using dmenu, and copies the corresponding OTP to the clipboard. Alternatively, it can "type" the OTP using xdotool on X11.

Notable features:

• Pick between all credentials on all connected YubiKeys

• No mouse interaction required

pcsc-lite provides an interface to communicate with smartcards and readers using the SCard API. pcsc-lite is used to connect to the PC/SC daemon from a client application and provide access to the desired reader.

Libu2f-host provides a C library and command-line tool that implements the host-side of the Universal 2nd Factor (U2F) protocol. There are APIs to talk to a U2F device and perform the U2F Register and U2F Authenticate operations.
