SOVEREIGN
PRIVACY.
Keypher is engineered for enthusiasts who reject metadata tracking. We don't hide your data; we make it invisible to the world.
Zero-Knowledge Base
Our architecture is "Blind" by design. We cannot see, leak, or sell what we do not possess.
No Central Vault
Your data only exists in plaintext on your device. On our servers, it is an opaque, random fragment of entropy.
Metadata Poisoning
We do not store your name, email, or device ID. Your identity is fragmented across our decentralized node network.
Argon2id Hardened
Your master password never leaves your browser. We only see the massive, memory-hard hash used for fragment retrieval.
Offline Priority
Keypher works perfectly without the internet. Sync is a choice, not a requirement for your sovereignty.
Blind Data Handling
The fragment protocol
When you "save" to the cloud, Keypher shards your vault into encrypted fragments. No single fragment contains usable data.
init_encryption
AES-256-GCM hardening happens locally within the user's isolated hardware environment.
init_cloud_shard
Shards are dispersed across high-security nodes. Retrieval requires your sovereign master key.
