## [0.1.0] - 2026-09-01
|
||||||
|
|
||||||
|
### Added
|
||||||
|
- Initial release of `wipe`
|
||||||
|
- Block device validation (`/dev` symlink resolution, block device checks)
|
||||||
|
- `lsblk --json` inspection with sysfs fallback
|
||||||
|
- Partition and mount discovery, nested mount handling
|
||||||
|
- Safety checks: whole-disk confirmation, mounted/swap detection, holder/dependency (LVM/dm-crypt/mdraid/multipath), running system protection
|
||||||
|
- HDD overwrite engine: zero, ones, alternating, random (ChaCha20 deterministic stream)
|
||||||
|
- Progress reporting via `indicatif`, ETA, throughput
|
||||||
|
- `sync` / `--no-sync`, deterministic verification (`OVERWRITE_VERIFIED`)
|
||||||
|
- SSD/NVMe backends: `secure-discard` (`blkdiscard --secure`), `nvme-sanitize`/`nvme-crypto` via `nvme-cli` with capability (`SANICAP`) and `SSTAT` monitoring
|
||||||
|
- CLI: `--passes`, `--method`, `--yes`, `--whole-disk`, `--unmount`, `--force`, `--dry-run`, `--verify`, `--buffer-size`, `--json`, `--verbose`
|
||||||
|
- JSON output with error codes (0-15)
|
||||||
|
- SIGINT handling (exit 15, `WIPE INTERRUPTED`)
|
||||||
|
- Loop device integration tests and unit tests
|
||||||
|
- CI (`cargo fmt`, `check`, `test`, `clippy`, `build`), release workflow, Dockerfile, Makefile

# wipe
|
||||||
|
|
||||||
|
Secure block device wipe and hardware erase orchestration for Linux — a safer, stricter alternative to `shred` for whole-disk operations.
|
||||||
|
|
||||||
|
> **Warning: This tool performs irreversible destructive operations.** Always verify the target device with `--dry-run` first.
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- Strict destructive-operation safety: `/dev` validation, symlink escape prevention, whole-disk confirmation, mount/swap/holder checks, running system protection
|
||||||
|
- HDD overwrite: `zero`, `ones`, `alternating`, `random` (ChaCha20 deterministic stream, per-chunk unique, verifiable)
|
||||||
|
- SSD/NVMe hardware erase: `secure-discard` (`blkdiscard --secure`), `nvme-sanitize` (block erase), `nvme-crypto` (crypto erase) via `nvme-cli`
|
||||||
|
- Progress, ETA, throughput, sync control, `--verify` (`OVERWRITE_VERIFIED`)
|
||||||
|
- Human and JSON output, typed exit codes (0-15), SIGINT-safe
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cargo install --path .
|
||||||
|
```
|
||||||
|
|
||||||
|
Or build release binary:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cargo build --release
|
||||||
|
# binary at target/release/wipe
|
||||||
|
```
|
||||||
|
|
||||||
|
## Build
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cargo build --release
|
||||||
|
```
|
||||||
|
|
||||||
|
## Basic Usage
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Dry run first!
|
||||||
|
sudo wipe /dev/sdb --whole-disk --dry-run
|
||||||
|
|
||||||
|
# Wipe HDD (1 pass zero overwrite, sync)
|
||||||
|
sudo wipe /dev/sdb --whole-disk
|
||||||
|
|
||||||
|
# Multiple passes
|
||||||
|
sudo wipe /dev/sdb --whole-disk --passes 3
|
||||||
|
|
||||||
|
# With verify
|
||||||
|
sudo wipe /dev/sdb --whole-disk --verify
|
||||||
|
|
||||||
|
# JSON output
|
||||||
|
sudo wipe /dev/sdb --whole-disk --json --yes
|
||||||
|
```
|
||||||
|
|
||||||
|
### Methods
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Auto (HDD -> zero, SSD/NVMe -> require explicit method)
|
||||||
|
sudo wipe /dev/sdb --whole-disk --method auto
|
||||||
|
|
||||||
|
# Explicit overwrite methods
|
||||||
|
sudo wipe /dev/sdb --whole-disk --method zero
|
||||||
|
sudo wipe /dev/sdb --whole-disk --method random
|
||||||
|
sudo wipe /dev/sdb --whole-disk --method ones
|
||||||
|
sudo wipe /dev/sdb --whole-disk --method alternating
|
||||||
|
|
||||||
|
# SSD / NVMe hardware erase
|
||||||
|
sudo wipe /dev/nvme0n1 --whole-disk --method nvme-sanitize
|
||||||
|
sudo wipe /dev/nvme0n1 --whole-disk --method nvme-crypto
|
||||||
|
sudo wipe /dev/sda --whole-disk --method secure-discard
|
||||||
|
```
|
||||||
|
|
||||||
|
- `auto` will not silently fallback from hardware erase to overwrite on SSD/NVMe; it returns an error requiring explicit `--method`.
|
||||||
|
- NVMe sanitize is asynchronous; `wipe` polls `nvme sanitize-log` (`SSTAT`) every second.
|
||||||
|
|
||||||
|
## Common Options
|
||||||
|
|
||||||
|
| Option | Description |
|
||||||
|
|---|---|
|
||||||
|
| `-n, --passes <N>` | HDD overwrite passes (default 1) |
|
||||||
|
| `-m, --method <METHOD>` | `auto` (default), `zero`, `random`, `ones`, `alternating`, `secure-discard`, `nvme-sanitize`, `nvme-crypto` |
|
||||||
|
| `-y, --yes` | Skip interactive `WIPE` confirmation (does NOT bypass system-disk protection) |
|
||||||
|
| `--whole-disk` | Explicitly allow whole-disk wipe |
|
||||||
|
| `--unmount` | Auto unmount filesystems / swapoff |
|
||||||
|
| `--force` | Override non-system safety checks (never bypasses running system device) |
|
||||||
|
| `--dry-run` | No data modification; shows device, partitions, mounts, method, passes |
|
||||||
|
| `--verify` | Read-back verification after overwrite |
|
||||||
|
| `--no-sync` | Skip final `sync` |
|
||||||
|
| `--buffer-size <SIZE>` | e.g. `64M` (default), `16M`, `32M`, `128M` |
|
||||||
|
| `--json` | Machine-readable output |
|
||||||
|
| `-v, --verbose` | Verbose logging |
|
||||||
|
|
||||||
|
Exit codes: `0` success, `1` generic, `2` invalid args, `3` perm denied, `4` not found, `5` not block device, `6` mounted, `7` dependency, `8` running system, `9` unsupported method, `10` capability unavailable, `11` unmount failed, `12` overwrite failed, `13` verification failed, `14` external command failed, `15` interrupted.

}
|
||||||
|
```
|
||||||
|
|
||||||
|
## SSD / NVMe vs HDD
|
||||||
|
|
||||||
|
- **HDD** (`ROTA=1`): `zero` overwrite is the default for `auto`. Use `--passes` for multiple passes.
|
||||||
|
- **SSD** (`ROTA=0`, SATA): Prefer `secure-discard` if supported; otherwise explicit `zero` overwrite with the caveat that logical overwrite ≠ NAND erasure.
|
||||||
|
- **NVMe**: Check `nvme id-ctrl` `SANICAP` (bit 0 crypto, bit 1 block, bit 2 overwrite). Use `nvme-sanitize` / `nvme-crypto` for controller-level erase. `auto` requires explicit method for SSD/NVMe to avoid silent fallback.
|
||||||
|
|
||||||
|
## Safety Notes
|
||||||
|
|
||||||
|
See [SECURITY.md](SECURITY.md). Logical verification (`OVERWRITE_VERIFIED`) confirms the LBA range reads back as written, but does not prove forensic irrecoverability for remapped sectors or NAND cells.

# Security Policy
|
||||||
|
|
||||||
|
## Destructive Operation Warning
|
||||||
|
|
||||||
|
**This tool performs irreversible destructive operations.**
|
||||||
|
|
||||||
|
Running `wipe` will permanently destroy all data on the target block device. This operation cannot be undone.
|
||||||
|
|
||||||
|
- Always verify the target device path (`lsblk`, `fdisk -l`) before running.
|
||||||
|
- Use `--dry-run` to preview what will happen without modifying data.
|
||||||
|
- The tool requires `--whole-disk` for whole-disk devices to prevent accidental wipes.
|
||||||
|
- Running system devices (`/`, `/boot`, `/boot/efi`, swap) are protected and will be refused even with `--yes` or `--force`.
|
||||||
|
|
||||||
|
## Logical Overwrite Limitations
|
||||||
|
|
||||||
|
Logical overwrite (zero, random, etc.) does **not** guarantee physical NAND erasure:
|
||||||
|
|
||||||
|
- Remapped sectors, SSD NAND cells, controller cache, and firmware-level storage may retain previous data.
|
||||||
|
- For SSDs/NVMe, prefer controller-level sanitize when supported:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
sudo wipe /dev/nvme0n1 --whole-disk --method nvme-sanitize
|
||||||
|
sudo wipe /dev/nvme0n1 --whole-disk --method nvme-crypto # if OPAL/crypto supported
|
||||||
|
sudo wipe /dev/sda --whole-disk --method secure-discard # for SATA SSD with secure discard
|
||||||
|
```
|
||||||
|
|
||||||
|
- Multiple overwrite passes do not necessarily improve erasure on flash media; controller-level operations are semantically different.
|
||||||
|
|
||||||
|
> **Logical read-back verification (`--verify` / `OVERWRITE_VERIFIED`) ≠ forensic proof of irrecoverability.**
|
||||||
|
|
||||||
|
Verification confirms that the logical LBA range reads back as written, but cannot prove that all physical media, spare areas, or controller caches have been erased.
|
||||||
|
|
||||||
|
## Reporting Vulnerabilities
|
||||||
|
|
||||||
|
If you discover a safety bypass or security issue (e.g., system disk protection can be bypassed, or the tool wipes an unintended device):
|
||||||
|
|
||||||
|
1. Do not publicly disclose immediately.
|
||||||
|
2. Open a security advisory via GitHub or contact the maintainer.
|
||||||
|
3. Provide steps to reproduce, device layout, and expected vs actual behavior.
|
||||||
|
|
||||||
|
## Safe Usage Checklist
|
||||||
|
|
||||||
|
- [ ] Confirmed device path with `lsblk --json` and `/dev/disk/by-id/`
|
||||||
|
- [ ] Ran with `--dry-run` first
|
||||||
|
- [ ] Verified device is not holding the running system
|
||||||
|
- [ ] Unmounted or used `--unmount` for filesystems
|
||||||
|
- [ ] Understood method semantics for your media type (HDD vs SSD vs NVMe)
