About Hash Generator
Product Documentation, Architecture & Offline Privacy Verification
What It Does
Generate SHA-256, SHA-384, and SHA-512 hashes from text or files entirely in your browser.
How It Works
Key Features
- 100% Client-Side Processing: Calculates hashes strictly within your browser using the native Web Crypto API for maximum privacy.
- Text & File Checksums: Instantly hash strings of text or generate file checksums up to 50MB to verify integrity.
- Modern Cryptography: Supports standard secure hashing algorithms including SHA-256, SHA-384, and SHA-512.
Limitations & Compatibility
Frequently Asked Questions
What is a hash?
A cryptographic hash is a one-way mathematical function that converts data of any size into a fixed-length string of characters. It acts like a unique digital fingerprint for your data.
What is SHA-256?
SHA-256 (Secure Hash Algorithm 256-bit) is a widely-used cryptographic hashing algorithm designed by the NSA. It generates an almost-unique, fixed size 256-bit (32-byte) hash. It is currently considered highly secure and is used in SSL certificates, blockchains, and password hashing.
What is the difference between SHA-256 and SHA-512?
SHA-512 is essentially a 512-bit version of SHA-256. It produces a longer, more secure digest and runs faster on 64-bit processors, while SHA-256 is typically faster on 32-bit systems.
Does KreateKode upload my files?
No. The hashing process utilizes the Web Crypto API built into your browser. Your files are processed entirely locally and are never transmitted to any external server.
Is hashing the same as encryption?
No. Encryption is a two-way function designed to be decrypted with a key. Hashing is a one-way function—you cannot reliably "decrypt" a hash back into the original text or file.
Why shouldn't I use MD5 for security?
MD5 is an older hashing algorithm that is cryptographically broken. It is vulnerable to collision attacks where two different files can produce the exact same MD5 hash. Modern security standards strongly recommend SHA-256 or higher.
