履歴

プロジェクトの歴史と使われ方

libyubikey is the C library inside Yubico yubico-c for low-level YubiKey one-time-password work: modhex conversion, OTP parsing, and OTP generation around the original Yubico authentication model.

プロジェクトの歴史

Yubico was founded in Stockholm in 2007 and launched YubiKey 1.0 in 2008 as a driverless one-touch OTP authenticator that identifies as a keyboard. yubico-c followed as the low-level C software development kit for the YubiKey authentication device.

The yubico-c repository describes the command-line tools that expose the library concepts: modhex converts between modhex, hex, and binary forms; ykparse decrypts and parses one OTP with the corresponding AES key; ykgenerate constructs and encrypts one OTP from key and internal token data.

採用の歴史

libyubikey belongs to the pre-FIDO YubiKey software stack, when OTP validation and provisioning were central to deploying hardware authentication. As Yubico and Google moved U2F into the FIDO Alliance in 2013 and browsers and services adopted FIDO U2F from 2014 onward, libyubikey remained relevant for legacy OTP integrations and tooling rather than newer WebAuthn flows.

Yubico announced end-of-life for yubico-c on February 19, 2025, with end-of-life scheduled for February 19, 2026. That makes the package historically important as part of the original YubiKey OTP era, even where newer Yubico libraries cover PIV, FIDO, OATH, or platform-specific use cases.

使われ方

Packagers expose libyubikey as a small C library plus tools for modhex and YubiKey OTP token work. It is most useful for test vectors, provisioning scripts, compatibility tooling, and software that needs to parse or generate Yubico OTP values without pulling in higher-level device-management stacks.

パッケージ好きにとっての重要性

For package nerds, libyubikey is a tiny security package with a lot of context packed into it: custom alphabets, AES-backed OTP fields, hardware-token history, man pages, Autotools, and a clear line from early two-factor authentication to later FIDO/WebAuthn ecosystems.

タイムライン

  • 2007: Yubico was founded in Stockholm and developed a YubiKey 1.0 prototype.
  • 2008: YubiKey 1.0 was launched.
  • 2010: Yubico added OATH one-time-password support to the YubiKey product line.
  • 2013: Yubico and Google contributed U2F technical specifications to the FIDO Alliance.
  • 2025-02-19: Yubico announced end-of-life for yubico-c.
  • 2026-02-19: Yubico scheduled yubico-c to reach end-of-life.

Related projects

  • yubico-c is the upstream source package for libyubikey. Related Yubico projects include higher-level YubiKey management and protocol libraries, while U2F, FIDO2, and WebAuthn represent the standards track that superseded many OTP-first deployments.
