Keys Stay Local: The Importance of End-to-End Encryption
Encryption is only as strong as your key management. When encryption keys are stored on your device rather than on a server, you maintain true control over your data.
Why Local Keys Matter
- No server compromise: Even if the service is hacked, your data stays encrypted
- No key extraction: Attackers can't extract keys from your device without physical access
- True ownership: You control encryption and decryption, not a third party
- Legal protection: Law enforcement can't compel you to hand over keys you don't have
How digital-footprint-health Uses Local Keys
- Your encryption key is generated on your device
- The key never leaves your computer
- We can't decrypt your data even if we wanted to
- You can verify encryption is working correctly
The Risk of Cloud-Stored Keys
When keys are stored in the cloud, you're trusting the service provider with the "keys to your kingdom." If they're compromised, your data is exposed regardless of encryption quality.
