プロジェクトの歴史

The project is maintained by CryptoTrust/trustcrypto and described upstream as an SSH agent for OnlyKey. PyPI's release history starts with 0.0.2 on March 11, 2018, reaches 1.0.0 on November 14, 2019, and lists 1.1.15 on July 21, 2023.

OnlyKey's documentation positions the agent as a way to keep SSH and OpenPGP private keys off the computer while still using ordinary SSH and GnuPG workflows. The agent uses OnlyKey button presses or challenge codes to authorize signing and decrypt operations.

採用の歴史

onlykey-agent is available from PyPI and Homebrew, and Homebrew's formula exposes its native dependencies on GnuPG, hidapi, libusb, libsodium, and Python. Its audience is narrower than general FIDO/U2F tooling because it specifically serves OnlyKey users who want SSH-agent and gpg-agent style integration.

使われ方

For SSH, users generate or expose a public key with onlykey-agent, add it to authorized_keys or a Git hosting account, and run commands inside an agent-backed shell or command wrapper. For GPG, users initialize a dedicated GNUPGHOME such as ~/.gnupg/onlykey and use onlykey-gpg for signing, encryption, and Git commit/tag signing.

The documentation distinguishes derived keys from stored keys. Derived keys are generated from identity@host-style inputs, while stored keys use key material loaded into OnlyKey slots, including ECC and RSA slots for SSH/GPG operations.

パッケージ好きにとっての重要性

The package is interesting because it turns a hardware-security product into normal Unix developer plumbing. The package exposes multiple executables, slots into SSH_AUTH_SOCK and GNUPGHOME conventions, and depends on USB/HID and cryptographic libraries rather than inventing a separate workflow.
