Secure Online Hash Generator
Cryptography is essential for modern web security. A Hash Function takes an input (or 'message') and returns a fixed-size string of characters, which is typically a 'digest' that is unique to the input. Unlike encryption, hashing is one-way: you cannot reverse the hash to get the original text.
Supported Algorithms
MD5 (128-bit)
Fast but arguably insecure for passwords due to collision vulnerabilities. Still widely used for file integrity checksums.
SHA-256 (256-bit)
The industry standard for security. Used by Bitcoin, SSL Certificates, and modern authentication systems. Extremely resistant to brute-force attacks.
Base64 (Encoding)
Technically not a hash, but an encoding scheme. It converts binary data into ASCII text. Commonly used to embed images directly into HTML or CSS.
Client-Side Security Guarantee
Most online hash generators send your data to their server to process it, which creates a security risk. ToolSurf processes everything in your browser. Your passwords, API keys, or text inputs never leave your device.
