Zero-Knowledge.
Zero Compromise.
At Cipherwill, your digital legacy is protected by client-side cryptography. Your secrets are encrypted on your device before they ever touch the cloud. We are entirely blind to your data-by design.
Built on Unshakable Pillars
A secure foundation built on client-side control and cryptographic openness.
Client-Side Encryption
All sensitive assets are locked using AES-256-GCM right in your browser or device app before they are uploaded. Your device holds the master key-never our servers.
Zero-Knowledge Architecture
We design our architecture so that Cipherwill is mathematically blind to your contents. Because we do not store or transmit your raw passwords or keys, we cannot access your digital will under any circumstance.
Open Source Transparency
Security shouldn't rely on blind faith. Our core cryptographic protocols, client-side encryption libraries, and smart-contract specifications are inspectable, open, and community-audited.
The Data Lifecycle
How your sensitive information is transformed from plaintext into unbreakable ciphertext.
Raw Data Provided
You enter sensitive items (passwords, files, wills) in our secure dashboard locally.
Client-Side Encryption
Your browser encrypts raw data with AES-256 before leaving your computer.
Sealed Zero-Knowledge Vault
Only ciphertext is stored in the cloud. It is completely unreadable to Cipherwill.
Beneficiary Unlock
Decryption occurs only on the verified beneficiary's device using their private key.
Peer-Reviewed
Mathematics.
We do not invent proprietary or closed security ciphers. Cipherwill is built strictly upon industry-standard, battle-tested cryptographic primitives, ensuring complete long-term protection.
AES-256-GCM Encryption
The gold standard of bulk data encryption. Encrypts all notes, files, credentials, and assets locally on your device with high-entropy keys.
BLS12-381 & SECP256K1
Advanced algebraic curves used for digital signature verification, zero-knowledge metadata checks, and secure, non-custodial key exchanges.
Shamir's Secret Sharing
Splits master contingency keys into multiple mathematical fragments (shards) held by independent verifiers to secure the Shard Switch.
Trust should be
mathematical,
not corporate.
We don't believe in security theater or blind faith. From server survivability to data subpoena protection, we have documented every policy in absolute, rigorous detail.
Confronting your deepest concerns.
How does Cipherwill verify my death before providing data to beneficiaries?
DetailsCipherwill releases access to your data based on the will execution timeline and verification of your death or inactivity.
What happens if my beneficiaries aren't tech-savvy? Is there support for them to access the data?
DetailsCipherwill ensures that your beneficiaries, regardless of their tech skills, can easily access your data with minimal effort.
Can my data be accessed or subpoenaed by governments or law enforcement agencies?
DetailsCipherwill ensures that your data is fully protected by encryption and can only be accessed by you or your beneficiaries.
