WHDIGO is the only standalone secret storage manager with quantum-resistant cryptography. No servers. No cloud. No compromises.
Enterprise-grade security without enterprise complexity
Runs completely offline with zero internet dependency. No servers, no cloud, no data transmission. Your vault stays on your device.
Military-grade Argon2id key derivation with AES-256-GCM encryption. WebAssembly-powered for native performance and quantum resistance.
All cryptographic libraries verified with SHA-384 Subresource Integrity (SRI) checks to prevent tampering and ensure authenticity.
Optional fragment storage splits your vault into 6 files with 4 decoys. Attackers can't identify real data, adding extreme protection.
All encryption happens in your browser. Your master password and data never leave your device. We can't access your vault even if we wanted to.
Passwords, crypto keys, passkeys, documents, QR codes, wallet seeds. If it's secret, WHDIGO protects it with military-grade encryption.

System utilizes 3 isolated, geographically independent nodes. No single point of failure detected. No History, just the last encrypted sharded data set.
Vault split into 6 mathematical fragments. Threshold set to 4. Requires consensus from 2+ nodes to decrypt.
Redundancy Check: System remains operational even if one server is down, compromised or destroyed.
API Security Headers enforced. Execution of unauthorized scripts prevented at the protocol level.

Built to withstand nation-state attacks and quantum computing threats
Your master password is processed through Argon2id, the gold standard for password hashing. This memory-hard algorithm resists GPU and ASIC attacks, making brute-force attempts virtually impossible.
All vault data is encrypted with AES-256-GCM, providing both confidentiality and authenticated encryption. This ensures data integrity and protects against tampering.
All cryptographic libraries are loaded with SHA-384 Subresource Integrity checks. This prevents malicious code injection and ensures you're always using authentic, unmodified crypto libraries.
Vaults can be split into two independently encrypted files, both files needed to view the vault. Attackers can't tell which files matter, exponentially increasing attack difficulty.
WHDIGO's cryptographic stack is designed to resist both current and future quantum computing attacks. Argon2id's memory-hard properties and AES-256's symmetric encryption remain secure even against quantum adversaries.
Three simple steps to absolute security
Set a strong master password. WHDIGO uses Argon2id to derive an encryption key that never leaves your browser.
Add passwords, crypto keys, documents, or any sensitive data. Everything is encrypted locally with AES-256-GCM.
Export as a single file or 6 secure fragments. Store on USB drives, encrypted cloud storage, or keep offline entirely.
