# Welcome to Rehide

## What is Rehide?

Rehide is the ultimate solution for safeguarding your secrets. It's a zero-knowledge, non-custodial password manager that allows you to encrypt your confidential information using your web3 wallet and securely store it as NFTs in your vault. 

Your secrets and passwords are never retained by Rehide; the only key to decrypting them is your original password or your web3 wallet's signature. Embrace this decentralized alternative to traditional password managers and regain full control and ownership over your sensitive data.

## How does Rehide's encryption work?

Every note is encrypted with a unique encryption key using an [AES-256-GCM](https://en.wikipedia.org/wiki/Galois/Counter_Mode) authenticated encryption scheme.

The encryption key is derived from an [Argon2id](https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html#argon2id) hash of a unique message signed by the user's wallet (or entered password) using the key derivation function [PBKDF2](https://en.wikipedia.org/wiki/PBKDF2).  Argon2id is the winner of the 2015 Password Hashing Competition and PBKDF2 is the recommended algorithm by NIST, according to [OWASP](https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html#pbkdf2).

In plain English, your secrets are secured with military-grade encryption. 

Currently, the U.S. government has named the AES-256 algorithm the standard for encryption and most cybersecurity organizations today use this form of military-grade encryption.
