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.

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.

Plocate is a locate based on posting lists, completely replacing mlocate with a faster and smaller index. It is suitable as a default locate on your system.

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.

YubiKey Manager (Qt) is a graphical application for configuring any YubiKey over all USB interfaces. For a CLI alternative, refer to the python-yubikey-manager package.

YubiKey C Client Library (libykclient) is a C library used to validate a one-time-password (OTP) YubiKey against Yubico’s servers. See the Yubico website for more information about Yubico and the YubiKey.

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.

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).

This package provides two libraries:

libp11

provides a higher-level (compared to the PKCS#11 library) interface to access PKCS#11 objects. It is designed to integrate with applications that use OpenSSL.

pkcs11prov

OpenSSL provider module that allows accessing PKCS#11 modules in a semi-transparent way.

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.

This is a C library that implements the server-side of the Universal 2nd Factor (U2F) protocol. More precisely, it provides an API for generating the JSON blobs required by U2F devices to perform the U2F Registration and U2F Authentication operations, and functionality for verifying the cryptographic operations.

This package provides a communication library for Nitrokey.

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.

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.

Pkcs11-helper is a library that simplifies the interaction with PKCS#11 providers for end-user applications. PKCS#11 is published standard. PKCS#11 is the de-facto standard to access cryptographic devices

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.

This Python library provides functionality for communicating with a Fast IDentity Online (FIDO) device over Universal Serial Bus (USB) as well as verifying attestation and assertion signatures. It aims to support the FIDO Universal 2nd Factor (U2F) and FIDO 2.0 protocols for communicating with a USB authenticator via the Client-to-Authenticator Protocol (CTAP 1 and 2). In addition to this low-level device access, classes defined in the fido2.client and fido2.server modules implement higher level operations which are useful when interfacing with an Authenticator, or when implementing a Relying Party.

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.

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.

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

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.

This package provides GUI tool that interfaces with Nitrokey Pro v0.7/v0.8 and Nitrokey Storage devices.

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

This is an OpenSSL provider to access hardware and software tokens using the PKCS#11 cryptographic token interface. Access to tokens depends on loading an appropriate PKCS#11 driver that knows how to talk to the specific token. The PKCS#11 provider is a connector that allows OpenSSL to make proper use of such drivers.
