It runs on an air-gapped computer and accepts unsigned spend objects, producing full or partial signatures suitable for multisig scenarios. The package includes utilities to generate secret keys, display public keys, merge multisig signatures, and convert between binary and qrint ASCII formats, plus debugging tools to inspect spend bundles and unsigned spends.\n\nThe tool is built on top of Chia's core libraries (chia_base and chialisp_puzzles) and the segno QR code library. It is intended for operators who need to keep signing keys isolated from networked systems, a common requirement in cryptocurrency custody workflows. The aging maintenance status suggests it is stable but not actively developed, so it may lag behind new Chia protocol features.","worth_installing":"Yes, if you are building or operating a Chia node that requires offline transaction signing. The low install friction and permissive license make it straightforward to add. However, verify compatibility with your Chia version and Python environment first, and understand that aging maintenance means you may need to maintain or patch it yourself if the Chia protocol evolves significantly."},"id":"hsms","links":{"html":"https://skillfed.io/packages/hsms","md":"https://skillfed.io/packages/hsms.md","pypi":"https://pypi.org/project/hsms/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-11-20","license_spdx":null,"license_treatment":"permissive","name":"hsms","python_support":"unspecified","summary":"Hardware security module simulator for chia bls12_381 signatures"},"popularity":{"monthly_downloads":108204,"position":12569,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.3.2"}
