Most digital evidence tools focus on chain-of-custody logging, but none of the ones I found address what happens when quantum computers make today's signatures forgeable — which matters a lot for evidence meant to hold up in court years from now. Quantum Blue is a Go CLI that signs and timestamps evidence using NIST's post-quantum standards (ML-DSA-65 for signatures, ML-KEM-768 for key exchange, hybrid with classical crypto so nothing breaks in the transition period), plus RFC 3161 timestamping and CBOM generation — built specifically to satisfy the certification requirements under Section 65B(4) of the Indian Evidence Act for electronic evidence. Started as a way to solve a real gap I kept running into: existing tools weren't built with post-quantum migration or legal admissibility in mind at the same time. Would love feedback from anyone working in digital forensics, legal tech, or PQC — especially on the CBOM format and whether the timestamping approach holds up to scrutiny.
