    1654 — encryption system

    1654 — encryption system

    1024-bit encryption system (functional safe or disk) | С++20

    This release marks the first production-ready publication of 1654, a dependency-free cryptographic vault engine built around a strict vault abstraction and a wide-state cryptographic design. 1654 is not a wrapper around existing crypto libraries. It is a self-contained system whose cryptographic behavior is fully defined within the repository. Key Characteristics Vault-oriented model Encrypted data is treated as a sealed container-safe with explicit operations, not as a password-wrapped file. Dependency-free design The entire cryptographic surface is auditable in-tree. PetoronHash as the cryptographic core All key material derivation, diffusion, and internal transformations are driven by PetoronHash 1024-bit wide internal state The architecture uses a wide internal state to increase diffusion depth and structural safety margins. ...

    AAD-50

    Zero-trust storage erasure. Hardware-verified data destruction.

    ...AAD-50 fixes this by polling NVMe Log Page 0x81 (Sanitize Status) after every cycle and refusing to advance until SSTAT=0x1 confirms hardware completion. Implements a 50-cycle B→C→A phase matrix: 40 cycles NAND overwrite, 5 FTL block erase, 5 crypto key destruction. Generates a SHA-256 audit chain and PDF Certificate of Destruction aligned with NIST SP 800-88 Rev.2 Purge and IEEE 2883.1-2025. Runs on Linux CLI, Windows CLI, and Windows GUI. Supports USB enclosure passthrough via 3-tier SCSI/ATA pathway. Adopted into linux-nvme/nvme-cli master (PR #3438) in 14 days.

    BIP39-XOR

    BIP39-XOR

    Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array ("seed")

    Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array (so-called "seed phrase") using exclusive OR (XOR)/Vernam cipher (a.k.a. One Time Pad). If not input by a user, an encryption key is automatically generated at random. Encryption with such a key preserves integrity of BIP-39 checksums of all keys (that's distinct while also compatible with SeedXOR implementation).
