QryptOn
Understand quantum cryptographic risk, check infrastructure readiness, and plan a structured migration toward crypto-agile and quantum-resistant systems.
A focused post-quantum service and technology ecosystem.
QryptOn combines practical education, a read-only readiness scanner, a browser-based cryptographic toolkit, migration guidance, and Qryptonite—Karsa's open-source pure-Rust PQC library.
Understand
Explain what quantum computers threaten, distinguish Shor and Grover impacts, and connect risks to current standards.
Check
Assess whether hosts can negotiate post-quantum TLS, SSH, and related capabilities through a scored readiness scan.
Act
Use browser-based demonstrations for hybrid key generation, encryption, and signing without sending keys or plaintext to the server.
Migrate
Build cryptographic inventory, risk-rank systems, deploy hybrid controls, rotate keys, and retire classical-only paths.
Migrate the right cryptography in the right order.
Cryptographic inventory
Find TLS, SSH, VPN, signing, database, backup, service-to-service, API, IoT, and appliance cryptography.
Risk-rank by data lifetime
Prioritize systems based on how long protected data must remain confidential and harvest-now-decrypt-later exposure.
Hybrid deployment
Introduce classical-plus-PQC constructions while preserving compatibility with systems that have not yet migrated.
Rekey and retire
Rotate long-lived keys, retire classical-only fallbacks according to risk, and repeat inventory continuously.
A transparent first step for existing infrastructure.
Security-conscious design
- Read-only execution
- No root access required
- No persistence or system configuration changes
- Bounded runtime and per-check time limits
- No result sharing unless explicitly enabled
Assessment coverage
- Post-quantum TLS negotiation readiness
- SSH and runtime capability checks
- Scored findings with concrete remediation
- POSIX support with lighter Windows coverage
- Machine-readable reporting options
The Rust library behind the QryptOn toolkit.
Qryptonite implements the algorithms specified by FIPS 203, 204, and 205 in pure Rust and provides modular crates for PQC, classical cryptography, hybrid constructions, high-level APIs, FFI, WebAssembly, and command-line use.
Pure Rust architecture
Avoids a C/CMake dependency and supports a clean WebAssembly build for browser tools.
Hybrid cryptography
Supports classical-plus-PQC constructions for migration scenarios and compatibility.
Verification practices
Relevant algorithm paths are tested against NIST ACVP vectors, with additional fuzzing and dependency checks described by the project.
Build cryptographic visibility and migration capability.
