Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text input.
About this tool
Free Hash Generator — MD5, SHA-1, SHA-256 & SHA-512 Online
Our free online hash generator computes MD5, SHA-1, SHA-256, and SHA-512 cryptographic hash values from any text input or file. Whether you're verifying file integrity for downloads, generating checksums for distribution, hashing passwords for development, or learning cryptographic hash concepts, our professional hash tool delivers instant accurate results with no signup or software installation.
Cryptographic hashes are essential for data integrity verification, password storage, digital signatures, blockchain technology, and software distribution. Our hash generator supports the most widely used algorithms — MD5 for legacy systems and quick checksums, SHA-1 for backwards compatibility, SHA-256 for modern security applications, and SHA-512 for high-security requirements. All hashing happens client-side in your browser for maximum privacy with no input data sent to our servers.
Key features
All Major Hash Algorithms
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text input or file uploads.
Text & File Hashing
Hash short strings, large text blocks, or upload files of any size for checksum verification.
Multiple Output Formats
Display hashes in lowercase hex, uppercase hex, or Base64 encoding depending on use case.
Client-Side Privacy
All hashing happens in your browser — input data never leaves your device, ensuring complete confidentiality.
