A hash function is a one-way cryptographic function that converts input data of any size into a fixed-size string of characters. Hash functions are used for data integrity verification, password storage, digital signatures, and blockchain technology.
Our hash generator supports SHA-256, SHA-512, SHA-1, and MD5. SHA-256 and SHA-512 are recommended for modern applications as they are more secure. MD5 and SHA-1 are provided for compatibility but are considered deprecated for security purposes.
Yes! All hashing happens locally in your browser using the Web Crypto API. Your input data never leaves your device - we don't store, transmit, or have access to any data you hash. Your privacy is completely protected.
Currently, the tool supports text input. For file hashing, you would need to convert the file to text first (e.g., using base64 encoding). We're working on adding direct file hashing support in the future.
Yes! Our hash generator is 100% free with no registration required, no usage limits, and no hidden fees. You can generate as many hashes as you need.
Hashes are commonly used for password verification, data integrity checks, digital signatures, blockchain transactions, file verification, and creating unique identifiers for data. They ensure data hasn't been tampered with.
