Trusted Timestamping for git repositories using RFC3161 and RFC5816 token
Trusted timestamps that you can physically include in photos, videos and live streams using QR codes and audible data signals.
Post-quantum trusted time-stamping server
Trusted Timestamping Framework for Scientific Research
Victor, verifier in cryptography, publicly issues free trusted TIMESTAMP of file hash information embedded into a blockchain.
Go client for the post-quantum Atum time-stamping service
Open e-science, workflow for collaborative academic writing, versioning, reviewing, research data management, time stamping and open access publishing
Alpha. Offline-first, end-to-end encrypted habitability evidence for tenant unions, with tamper-evident media, sourced timelines, RFC 3161 timestamps, peer-to-peer sync, repair letters, and verifiable review packets. No independent security or legal review, and no tenant-union pilot yet.
Command line tool for signing and timestamping PDF Files using certificates from Windows Certififcate Store, PKCS#12 files and PKCS#11 dongles
Self-hosted RFC 3161 and Microsoft Authenticode timestamp authority for Windows Server and IIS, supporting code and document signing with RSA and ML-DSA.
EverWitnessed protocol: timestamp any file on the Hive blockchain. Five-field JSON in a custom_json or transfer memo, verifiable from any Hive node. MIT.

Журнал работы ИИ-системы, который нельзя незаметно изменить задним числом: пломбу на записи ставит третья сторона, проверка работает офлайн
A Decentralized Trusted Timestamp Authority.
Proof of existence for any file via trusted timestamping: RFC 3161 timestamps from three independent authorities (FreeTSA, DigiCert, Sectigo). One Bash script: only the hash leaves your computer, and the proofs pack into a self-contained archive that verifies offline.
Cryptographic evidence preservation in one auditable Bash script: deterministic SHA-256 manifest, opt-in RFC 3161 timestamp, and a signable attestation. Linux and macOS.
Hash-chained single-writer authorship ledger with honesty-graded timestamp receipts and a zero-trust, offline, portable verification package
Cross-platform portable desktop app for applying RFC 3161 trusted timestamps to PDF files with batch processing, smart PDF repair, and privacy-focused local processing.
Browser-based chain of custody for digital evidence: SHA-256 hash chain, RFC 3161 timestamping, EXIF capture, offline verification. Vanilla JS, zero runtime dependencies, MIT.
