FileSigner Pi 2.0

FileSigner Pi by tcs is a lightweight, secure tool for creating and verifying digital signatures on files of any size. Built for developers, IT teams, and security-conscious organizations, it streamlines integrity and authenticity checks across build pipelines, release workflows, and day-to-day file exchange. With sensible defaults, clear feedback, and flexible automation options, FileSigner Pi makes trustworthy distribution simple without compromising on cryptography or control.

Key capabilities:

• Create and verify signatures using industry-standard algorithms (RSA, ECDSA, Ed25519) and hashes (SHA-256/384/512)
• Work with X.509 certificates and private keys from common formats (PEM, PKCS#12), with support for detached or embedded signatures
• Add trusted timestamps via RFC 3161 timestamp authorities to strengthen non-repudiation
• Validate signer identity, certificate chains, and revocation status (OCSP/CRL)
• Run at scale with batch and recursive signing, plus JSON logs and clear exit codes for CI/CD
• Choose the interface that fits your workflow: straightforward CLI for automation and a clean, guided UI for manual tasks
• Integrate securely with system keychains and hardware tokens/HSMs through PKCS#11
• Operate offline when needed and minimize dependencies for easy deployment
• Receive detailed verification reports that are audit-friendly and easy to parse

Whether you are releasing software, distributing internal artifacts, or safeguarding backups and documents, FileSigner Pi helps you prove provenance and preserve integrity with speed, clarity, and confidence.
