Your Secrets, Mathematically Guaranteed Private
Why SparkVault Is Different
Most "secure" storage providers can decrypt your data if compelled. We literally cannot.
Triple Zero-Trust
Decryption requires three independent keys: ours, hardware-secured, and yours. No single party—including us—can ever access your plaintext data alone.
Quantum-Safe Now
NIST-standardized ML-KEM-1024 (CRYSTALS-Kyber) post-quantum cryptography protects your data against future quantum computing threats today.
Hardware Isolation
Cryptographic operations happen inside hardware-isolated Trusted Execution Environments. Keys never exist in accessible memory.
Two Products, One Principle
Whether you need ephemeral secrets or persistent encrypted storage, your data stays private.
Sparks
Burn After Read
Share secrets that self-destruct after a single read. Perfect for passwords, API keys, and sensitive links. Set a TTL up to 24 hours, share the link, and it's gone forever after access.
- Auto-destroys after first read
- Maximum 24-hour TTL
- Up to 250KB per spark
- Double zero-trust encryption
Vaults & Ingots
Persistent Encrypted Storage
Create encrypted vaults protected by your passphrase. Store ingots (encrypted objects up to 5TB) with unlimited reads. Your passphrase never leaves your device—we can't help you if you lose it.
- Triple zero-trust (we literally can't decrypt)
- Unlimited reads per ingot
- Up to 5TB per ingot
- Post-quantum cryptography
The Math Behind the Promise
Our security isn't based on trust or policy. It's based on cryptographic impossibility.
All three keys are required to decrypt. We hold one. Hardware holds one. You hold one.
A subpoena, a breach, or a rogue employee cannot compromise your data—we don't have all the keys.
Use Cases
From ephemeral password sharing to long-term encrypted backups.
Secure Password Sharing
Create a Spark, share the link, recipient reads once—it's gone forever. No more passwords in Slack.
API Key Distribution
Onboard new developers with one-time access to credentials. Keys never sit in email or chat history.
Encrypted Backups
Store database backups, config files, or certificates in Vaults. Even if we're breached, attackers get ciphertext.
Compliance-Ready Storage
Store PII, PHI, or financial data knowing auditors can verify the mathematical impossibility of provider access.
Team Credential Management
Shared vaults let teams access secrets securely. Revoke access instantly without rotating everything.
Recovery Codes & 2FA Seeds
Store TOTP seeds, recovery codes, and authentication secrets with true zero-knowledge security.
Enterprise Security Standards
Built on NIST-standardized cryptography with full compliance certifications.
