Hash Generator & Verifier — User Guide
A suite of tools for client-side cryptographic hashing, file checksum computation, batch processing, and intelligent hash verification. Everything runs 100% locally in your browser — no network calls, nothing leaves the page.
Key Features & Modes
1. Text Hasher & All Digests View
- Supported Algorithms: MD5, SHA-1, SHA-256, SHA-384, SHA-512.
- Compute All Digests: Toggle Compute All Digests to see all 5 algorithms side-by-side in real-time.
- HMAC Signatures: Keyed-hash message authentication code support for SHA algorithms with a secret key.
- Prefix & Suffix Salting: Add custom salt values before or after input text.
- Output Formats: Toggle output between hex (lowercase), HEX (UPPERCASE), and Base64.
2. Drag & Drop File Checksum Hasher
- Drop any file (ZIP, ISO, APK, PDF, images, binaries) to compute MD5, SHA-1, SHA-256, and SHA-512 checksums instantly.
- Processed 100% locally via Web Crypto API.
3. Batch Multi-Line Hasher
- Paste multi-line text to hash multiple strings in a single pass.
- Export results directly to a CSV file or copy individual hashes.
4. Smart Verifier with Auto-Detection
- Paste an expected candidate hash (e.g., 32 characters for MD5, 64 for SHA-256).
- Automatically detects the algorithm type based on hash length and displays a PASS / FAIL verification indicator.
