About This Tool

The MKey Generator Switch offers on-demand key creation for development and testing. It accepts an algorithm choice, a key size, and an optional seed to determine determinism. The approach is designed for quick prototyping and integration testing without external dependencies. The tool supports two modes: deterministic derivation from a seed using a KDF with a counter, and non-deterministic generation from a cryptographically secure RNG. Outputs can be presented in hex, base64, or base32 to fit various workflows. Core use cases include creating mock credentials for automated tests, validating key handling in apps, and demonstrating rotation concepts in demos. Unlike full KMS solutions, this tool does not store keys or manage lifecycle, focusing strictly on generation and formatting. By separating deterministic and non-deterministic paths, it helps teams verify reproducibility requirements while preserving realistic randomness when needed. The design emphasizes safe, transient key material with clear export options to downstream systems or test harnesses.

How to Use

Provide inputs: choose algorithm, set key_size (bits), and enter seed when deterministic mode is chosen.
Choose mode: deterministic for repeatable keys or non-deterministic for randomness.
Run calculation: generate the key material using the selected method.
Review outputs: inspect key value, length, and encoding (hex/base64/base
.
Export or copy: save to a file or copy to clipboard in the desired encoding.

Frequently Asked Questions

Find Quick Answers

What is the difference between deterministic and non-deterministic mode?

Deterministic mode uses a seed and a KDF to reproduce the same key for the same inputs, which is ideal for testing and demos. Non-deterministic mode relies on a cryptographically secure RNG to produce unique keys each time, suitable for more realistic scenarios.

Can I generate multiple keys in sequence?

Yes. In deterministic mode you can increment a counter or use multiple seeds to derive a sequence of keys. In non-deterministic mode, each run produces a fresh random key, which can be managed by your calling workflow.

Is this suitable for production-grade security?

No. This tool is intended for testing, prototyping, and demonstrations. Production-grade security requires a proper Key Management System (KMS) or hardware security module (HSM) with vetted policies and lifecycle controls.

Which encodings are supported?

Hex, base64, and base32 encodings are supported for interoperability. Choose the encoding that best matches your integration or logging requirements.
