Hash Generator

A hash function converts any input into a fixed-length string of characters. SHA-256 produces a 64-character hexadecimal digest and is used for file integrity checks, digital signatures, blockchain verification, and password storage. The same input always produces the same hash, but the process cannot be reversed.

SHA-256 is the most widely recommended for security and integrity verification. SHA-512 provides a longer 128-character hash for higher-security applications. SHA-1 is considered cryptographically weak and should only be used for legacy compatibility or non-security checksums like Git commit hashes.

Yes. All hashing runs entirely in your browser using the Web Crypto API. Your text and files are never uploaded to any server. You can safely hash sensitive documents, passwords, or confidential data without any privacy risk.

Yes. Drag and drop a file or click to select one, and the tool reads it locally in your browser to compute the hash. The file content never leaves your device. This works with files of any type and size that your browser can handle.

Generate the hash of your downloaded file, then paste the expected hash from the source website into the comparison section. The tool tells you whether the two hashes match. A match confirms the file has not been corrupted or tampered with during download.
