About this tool
Hash Generator is a free online developer tool. MD5/SHA-1/SHA-256/SHA-512 hash calculator. Built for coders and engineers who want less friction. It runs entirely in your browser — no download or sign-up needed.
After entering text or uploading a file, select a hash algorithm, and the tool calculates and displays the hash value. Supports common algorithms such as MD5, SHA-1, SHA-256, SHA-384 and SHA-512. Comparisons of the results of multiple algorithms can be calculated simultaneously. File uploading supports drag-and-drop, and the flow calculation of large files will not block the browser.
The hash calculation is implemented using the Web Crypto API (browser native encryption interface) or pure JavaScript. Web Crypto is a synchronization API that does not block the main thread. For file hashes, use FileReader to read blocks of data and update the hash calculation block by block.
It is suitable for verifying file integrity (comparing hash values for consistency after download), or generating cryptographic hashes (although actual projects should use a dedicated algorithm such as bcrypt). It is also used to generate unique identifiers when deduplicating data.
Hash value generation tool, which calculates MD5, SHA-1, SHA-256, SHA-512 and other hash values of text or files, supports Batch Compute and comparison.
