Hash Generator
What is a Hash Generator?
A hash generator is a tool that computes a fixed-size string of bytes from input data of any size. Hash functions are fundamental in cryptography, data integrity verification, and digital signatures. Each hash algorithm produces a unique fingerprint of the input data.
How to Use
- Enter your text in the input area or upload a file

- Use the uppercase toggle to change hash display format
Features
- Supports MD5, SHA-1, SHA-256, SHA-512, and CRC32
- Both hex and base64 output formats
- File hashing support for any file type
- All processing happens in your browser - no data sent to servers
FAQ
Is MD5 still secure?
MD5 is no longer considered cryptographically secure. It's vulnerable to collision attacks. Use SHA-256 or SHA-512 for security-sensitive applications. MD5 is still useful for checksums and non-security purposes.
What is CRC32 used for?
CRC32 is a fast checksum algorithm used primarily for error detection in data transmission and storage. It's commonly found in ZIP files, PNG images, and network protocols.
Are my files uploaded to a server?
No. All hashing is performed client-side in your browser using the Web Crypto API. Your files never leave your device.
