Introduction
Bitcoin wallet security remains one of the most critical aspects of cryptocurrency ownership. This HTML-based encryption tool provides a lightweight solution for protecting your wallet files using modern web standards. Unlike traditional software that requires installation, this solution runs entirely in your browser while maintaining robust security through the WebCrypto API.
Key Features
Advanced Wallet Protection
- AES-GCM encryption - Military-grade algorithm implementation
- Password-based security - User-controlled access
- SHA-256 hashing - Same cryptographic standard that secures Bitcoin itself
File Format Compatibility
Encrypt various wallet storage formats including:
- Plain text files (.txt)
- Documents (Word, PDF, Excel)
- Images (JPEG, PNG)
- Archives (ZIP, RAR)
Zero-Installation Convenience
👉 Browser-based security with enterprise-grade protection - no downloads required
Technical Implementation
WebCrypto API Integration
The system leverages modern browser capabilities through:
- Secure key derivation (PBKDF2)
- Authenticated encryption (AES-GCM)
- Cryptographic hashing (SHA-256)
Security Architecture
| Component | Function | Security Benefit |
|--------------------|-----------------------------------|----------------------------------|
| Password Input | User authentication | First security layer |
| SHA-256 Hashing | Password preprocessing | Prevents rainbow table attacks |
| AES-GCM Encryption | Data transformation | Confidentiality + integrity |Step-by-Step Usage Guide
Encryption Process
- Select your wallet file
- Enter strong password (minimum 12 characters recommended)
- Confirm password
- Generate encrypted HTML file
Decryption Process
- Open encrypted HTML file
- Authenticate with correct password
- Retrieve original wallet content
Security Considerations
Potential Risks
- Brute force attacks (mitigated by strong passwords)
- Network sniffing (avoid using on public networks)
- Social engineering (remain vigilant)

FAQ Section
Q: Is this tool safe for large Bitcoin holdings?
A: While the encryption is strong, we recommend this only for small amounts due to its experimental nature. Consider hardware wallets for significant holdings.
Q: What happens if I forget my password?
A: Like Bitcoin itself, there's no recovery option. The encryption is designed to be truly secure against all access attempts without the password.
Q: Can I use this offline?
A: Yes! After loading the page once, you can save it and use it completely offline for enhanced security.
Q: How does this compare to wallet.dat encryption in Bitcoin Core?
A: This provides similar security through different technical means - both use AES encryption, but this solution is more portable.
