About This Tool
What is Hash Generator?
Our Hash Generator creates cryptographic hashes for text and files using all major industry-standard algorithms: MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Switch between Text and File input using the source tabs, type or paste any text, or drag-and-drop a file — then click Generate Hashes to compute all five algorithms at once.
Need HMAC authentication codes? Enable HMAC mode and enter a secret key to generate keyed hashes for API authentication and data integrity verification. Prefer Base64 over hex? Toggle Base64 output with one click. Each result shows the algorithm name, its bit-strength badge, the hash value, and an individual Copy button — or use Copy All and Download TXT to grab everything at once.
Switch to the Verify Hash tab to check whether a file or piece of text matches a known hash. Choose the algorithm, paste the expected hash, and the tool instantly tells you Match or No Match — showing both the computed and expected hashes side by side so you can spot any discrepancy.
All computation happens locally using the Web Crypto API (SHA family) and a pure-JS MD5 implementation. Nothing ever leaves your browser — no uploads, no tracking, complete privacy.
Features
Powerful Features
Everything you need in one amazing tool
Five Algorithms at Once
MD5, SHA-1, SHA-256, SHA-384, SHA-512 — all generated in a single click. Each result shows its bit-strength badge.
Text & File Hashing
Use the Text tab to hash any string, or switch to the File tab for drag-and-drop file hashing. Supports any file type and size.
HMAC Signing
Enable HMAC mode and enter a secret key to generate keyed hashes — useful for API authentication and message integrity.
Hash Verification
Switch to the Verify Hash tab, paste an expected hash, and instantly see Match or No Match with both hashes shown side by side.
Hex & Base64 Output
Toggle between standard hex output and Base64 encoding. Also supports uppercase hex for APIs that require it.
Secure & Private
All hashing uses the Web Crypto API and a local MD5 implementation. Files and text never leave your browser.

Frequently Asked Questions
Everything you need to know about Hash Generator
A cryptographic hash is a fixed-length string generated from data using a mathematical algorithm. It's like a digital fingerprint - unique to the input data. The same input always produces the same hash, but even a tiny change (like one character) produces a completely different hash, making it perfect for detecting any modifications to data.
For modern security needs, use SHA-256 or SHA-512. MD5 and SHA-1 are considered weak for cryptographic purposes but still useful for checksums and non-security applications. SHA-256 offers excellent security and is widely supported. SHA-512 provides even stronger security for highly sensitive applications.
No! Hashing is a one-way function - it's mathematically impossible to reverse. This is exactly why hashes are used for password storage - even if someone steals the hashed passwords from a database, they can't recover the original passwords. However, weak passwords can be vulnerable to dictionary attacks where attackers try hashing common passwords.
Download the file, then upload it to our hash generator using the same algorithm the provider used (usually MD5 or SHA-256). Compare the generated hash with the checksum provided by the download source. If they match exactly, the file is authentic and uncorrupted. Even one bit difference will produce a completely different hash.
MD5 is no longer considered secure for cryptographic purposes as collision attacks are possible. However, it's still perfectly fine for checksums, file verification, and detecting accidental corruption. For password hashing or digital signatures, use SHA-256 or stronger algorithms.
Absolutely not! All hashing happens entirely in your browser using the Web Crypto API. Your files and text never leave your device or get uploaded to any server. The tool works completely offline once loaded, ensuring total privacy and security.
