Developer of Ombracrypt. Focused on building open-source, air-gapped security tools, data sovereignty, and quantum-safe cryptography.

### [I couldn’t find a local Post-Quantum file encryption tool, so I built my own. Looking for feedback. Any thought on this ?](https://ombracrypt.hashnode.dev/post-quantum-vault-veracrypt-alternative?utm_source=hashnode&utm_medium=feed)

Post-quantum encryption vault & alternative to VeraCrypt, Picocrypt, Cryptomator, AxCrypt & 7-Zip against cloud & OS-level data privacy threats.
