libtocc is the engine of the Tocc project, a tag-based file management system. The goal of Tocc is to provide a better system for classifying files that is more flexible than classic file systems that are based on a tree of files and directories.

Xapers is a personal document indexing system, geared towards academic journal articles build on the Xapian search engine. Think of it as your own personal document search engine, or a local cache of online libraries. It provides fast search of document text and bibliographic data and simple document and bibtex retrieval.

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

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.

Search::Xapian wraps most methods of most Xapian classes. The missing classes and methods should be added in the future. It also provides a simplified, more 'perlish' interface to some common operations.

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.

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.

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.

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

Ugrep is a ultra fast searcher of file systems, text and binary files, source code, archives, compressed files, documents, and more.

While still being compatible with the standard GNU/BSD grep command-line options, ugrep supports fuzzy search as well as structured and (adjustable) colored output, piped through "less" for pagination. An interactive query UI allows refinement and has a built-in help (press F1). Ugrep implements multi-threaded and other techniques to speed up search, pattern-matching and decompression. Many pre-defined regexps ease searching e.g. C typdefs or XML attributes. Results can be output in several structured or self-defined formats.

Xapian is a highly adaptable toolkit which allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also supports a rich set of boolean query operators.

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.

Tocc is a tag-based file management system. This package contains the command line tool for interacting with libtocc.

Xapian is a highly adaptable toolkit which allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also supports a rich set of boolean query operators.

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

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 package provides a communication library for Nitrokey.

This package includes the IFD driver for the cyberJack contactless (RFID) and contact USB chipcard readers.

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.

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

This application provides support for using private and governmental e-services, signing and encrypting DigiDoc documents, and configuring Estonian ID cards. It requires a running pcscd service and a compatible card 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.

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

Client-side Python library for managing Nitrokey NetHSM HSMs.
