⚡ Why InterEnv?
Every software engineer, Web3 validator, and AI agent builder uses environment variables to store mission-critical credentials: INTERLAYER_VALIDATOR_KEY, ETHEREUM_PRIVATE_KEY, OPENAI_API_KEY, AWS_SECRET_ACCESS_KEY, database connection strings, and webhook signing secrets.
- ❌ The Catastrophic Problem: Plaintext
.envfiles get accidentally committed to public GitHub repositories daily. Maliciousnpmandpippackages scan developers' hard drives to exfiltrate plaintext secrets. In blockchain environments, a leaked.envmeans permanent loss of validator stake or treasury funds. - ❌ The Flaw in Other Tools:
dotenvxencrypts secrets but stores the decryption key in another plaintext file (.env.keys) on disk! Cloud secret managers (1Password, Doppler, Infisical) are cloud-locked, slow, and require expensive monthly subscriptions. - 🛡️ The InterEnv Solution: Engineered originally to safeguard high-stakes validator keys and autonomous agent secrets for the Interlayer Blockchain ecosystem, InterEnv seals your project secrets inside your Host Hardware Security Enclave (Apple Secure Enclave on macOS, TPM 2.0 / Windows Hello on Windows, Secret Service on Linux). Secrets are decrypted strictly in volatile process memory for the exact lifecycle of your command, and then erased with cryptographic zeroization (
zeroize).

💡 Quickstart in 10 Seconds
1. Seal Your .env into Hardware Enclave
Inside any project with an existing .env file:
interenv lock
What happens:
- Generates an XChaCha20-Poly1305 master project key and binds it to your Hardware Enclave (TouchID / TPM / Windows Hello).
- Creates an encrypted, git-safe
.interenv.lockfile. - Cryptographically shreds and destroys the plaintext
.envfrom physical storage using DoD 5220.22-M 3-pass overwriting!
2. Run Any App with Secrets in Volatile Memory
Execute any tool, test runner, validator node, or web server:
# Interlayer Blockchain Node / Validator / Contract Deployment interenv run interlayer-node --validator # Node / Next.js / Web3 interenv run npm run dev # Rust interenv run cargo run # Python / AI Agents interenv run python app.py # Docker / Go / Any Binary interenv run docker compose up
Secrets are injected directly into child process memory. Nothing ever touches disk.
3. Edit Secrets Safely
Need to add a new API key?
interenv edit
Opens your default $EDITOR in a secure temporary buffer, updates keys, re-encrypts into .interenv.lock, and securely shreds the temp buffer.
4. Install Git Pre-Commit Protection
interenv hook install
Installs an automated guard in .git/hooks/pre-commit that detects and immediately aborts any accidental staging or commit of .env files or hardcoded API keys.
💻 Multi-Language Programmatic SDKs
InterEnv provides native, zero-dependency SDKs across all major programming ecosystems. Secrets are injected directly into process memory without creating or touching plaintext .env files on disk.
Node.js & TypeScript
npm install interenv
import { config } from "interenv"; config(); // Injects into process.env in-memory console.log(process.env.OPENAI_API_KEY);
Python & AI Agents
pip install interenv
import interenv, os interenv.load_env() # Injects into os.environ in-memory print(os.getenv("OPENAI_API_KEY"))
Go Microservices
go get github.com/Bharathcoorg/interenv/go/interenv
package main import ( "fmt" "os" "github.com/Bharathcoorg/interenv/go/interenv" ) func main() { interenv.Load() // Injects into os.Setenv in-memory fmt.Println(os.Getenv("OPENAI_API_KEY")) }
PHP & Laravel
composer require bharathcoorg/interenv
use InterEnv\InterEnv; InterEnv::load(); // Injects into $_ENV, $_SERVER, and putenv() echo getenv('OPENAI_API_KEY');

🔒 Security Model & Guarantees
- Authenticated Encryption (AEAD): All environment payloads are encrypted with XChaCha20-Poly1305 using 192-bit (24-byte) random nonces sourced from the OS RNG (
rand::rngs::OsRng). - Hardware Enclave Sealing: Master encryption keys are stored directly in the host OS credential enclave:
- macOS: Apple Keychain backed by Apple Secure Enclave & TouchID (
macos-secure-enclave-v1). - Windows: Windows Credential Manager protected by TPM 2.0 (
windows-ncrypt-tpm-v2) and DPAPI. - Linux: TPM 2.0 hardware primary key binding (
linux-tpm2-v1) or FreeDesktop Secret Service.
- macOS: Apple Keychain backed by Apple Secure Enclave & TouchID (
- Headless & CI/CD Support: For automated CI runners and Docker containers, pass
--passphraseor setINTERENV_PASSPHRASEto derive master keys via Argon2id (memory-hard password hashing with OWASP defaults: 19 MiB RAM, 2 iterations, parallelism = 1). - Memory Zeroization: Plaintext secret buffers implement
zeroize::ZeroizeOnDrop, ensuring keys and values are actively wiped from RAM upon release.
Security Guarantees Table
| Vector | Guarantee | Implementation |
|---|---|---|
| Disk Inspection | Zero Plaintext | Master key sealed in OS hardware vault; .env shredded immediately. |
| Peer Process Sniffing | Process Sandbox | Linux Seccomp BPF filter; macOS Sandbox profile; Windows Job Object. |

Note
Linux TPM 2.0 Hardware Binding: Real Linux TPM 2.0 hardware binding requires building with --features tpm (cargo build --release --features tpm).
Without this flag or on machines lacking /dev/tpmrm0, Linux automatically utilizes secure Freedesktop Secret Service / software KEK protection.
Warning
Windows Job Object Isolation & unsafe_mode Feature:
Windows builds strictly enforce kernel Job Object isolation with JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE to ensure all spawned child trees terminate immediately when interenv exits.
The optional Cargo feature unsafe_mode allows INTERENV_UNSAFE=1 to bypass Windows Job Object isolation for headless or virtualized CI runners that lack nested Job Object permissions.
Never compile or enable unsafe_mode in production environments.
⚠️ Limitations
- Root / Ring-0 Access: An attacker with root or kernel privileges on the local machine can dump arbitrary memory.
- Solid State Drive Wear-Leveling: CoW filesystems (APFS, Btrfs, ZFS) and SSD flash translation layers (FTL) may wear-level blocks. InterEnv applies filesystem decommit calls (
fallocate,BLKDISCARD,SetFileValidData) and warns ininterenv doctor. - Hardware Failure / Reinstall: If a machine-bound TPM is reset, locally sealed lockfiles cannot be retrieved without an Argon2id passphrase backup (
interenv lock --passphrase).
🛡️ Audits & Reviews
InterEnv has undergone multi-phase adversarial security hardening:

❓ Frequently Asked Questions
What is InterEnv?
InterEnv is a high-performance, local-first secret management engine written in Rust that permanently eradicates plaintext .env files from developer disks. It binds encrypted project secrets directly to host hardware security enclaves (Apple Secure Enclave on macOS, TPM 2.0 / DPAPI on Windows, and Linux Secret Service) and decrypts them exclusively into volatile process memory.
Why was InterEnv engineered for Interlayer Blockchain?
Interlayer Blockchain is a sovereign multi-VM Layer 1 architecture designed for high-throughput consensus, decentralized validators, and autonomous on-chain AI agents. In high-stakes blockchain infrastructure, relying on external cloud secret managers introduces latency bottlenecks and vendor lock-in, while storing validator keys, relayer secrets, or deployer credentials in plaintext .env files risks catastrophic financial compromise. InterEnv was engineered to provide host silicon-level hardware isolation (Apple Secure Enclave and TPM 2.0) so that validator operators, node engineers, and autonomous Web3 agents can execute commands with zero plaintext exposure on physical disk.
How is InterEnv different from dotenv, dotenvx, and dotenv-vault?
dotenv: Leaves all API keys, database passwords, and private tokens unencrypted on physical storage, exposing them to rogue npm/pip supply-chain packages and accidental git commits.dotenvx: Encrypts.envfiles but writes the decryption master key to an unencrypted.env.keysfile on the exact same disk.dotenv-vault/Doppler/Infisical: Require proprietary cloud vaults, persistent internet connections, and paid monthly subscriptions.InterEnv: 100% offline, local-first, free & open source (MIT), binds keys to host hardware chips (TPM 2.0 / TouchID), and cryptographically destroys plaintext files using 3-pass DoD 5220.22-M overwrites.
How do AI Coding Agents (Cursor, Claude Desktop, Windsurf) safely use InterEnv?
AI coding agents execute your application via interenv run <command> or import the language SDK (interenv.config() in Node.js, interenv.load_env() in Python, interenv.Load() in Go, InterEnv::load() in PHP). Secrets are injected directly into the child process memory space via standard environment variables without ever creating a plaintext .env file on disk. This prevents LLMs, indexing bots, or repository search tools from reading or exfiltrating raw credentials.
How does InterEnv run in headless Docker containers and CI/CD pipelines?
When sealing a project for multi-developer or continuous integration workflows, run interenv lock --passphrase. In your automated CI runner (GitHub Actions, GitLab CI, Docker, Kubernetes), provide the secret passphrase through the INTERENV_PASSPHRASE environment variable along with INTERENV_CI=1. InterEnv derives the master key via OWASP-compliant memory-hard Argon2id (19 MiB RAM, 2 iterations, 1 parallelism) without interactive terminal prompts.
