Your documents are encrypted before they leave your device. We never see your data.
Zero-knowledge architecture ensures that MeCentral servers never have access to your unencrypted documents. All encryption happens in your browser before any data is transmitted.
// Encryption happens in your browser
const encryptDocument = async (document) => {
// Generate unique document key
const docKey = sodium.crypto_secretbox_keygen();
// Encrypt document with key
const encrypted = sodium.crypto_secretbox_easy(
document,
nonce,
docKey
);
// Seal key with your master key
const sealedKey = sodium.crypto_box_seal(
docKey,
userPublicKey
);
// Server only receives encrypted data
return { encrypted, sealedKey };
