Hash Generator
Generate and compare cryptographic digests for the same text. MD5, SHA-256, and SHA-512 run locally — your input never leaves the device.
Result
Enter text, choose algorithms, then Hash. Digests are computed locally.
How to generate hashes
- Enter the text to hash.
- Select one or more algorithms (MD5, SHA-256, SHA-512). MD5 loads on demand.
- Click Hash to compute the selected digests.
- Copy individual digests or all results. Encoding is UTF-8.
FAQ
- No. SHA-256 and SHA-512 use the Web Crypto API in your browser. MD5 uses spark-md5, loaded only when you select MD5 or open the MD5 generator.
- Different systems expect different digests. This page lets you verify the same string under MD5, SHA-256, and SHA-512 without switching tools.
- MD5 is not safe for passwords or signatures. It remains common for legacy checksums and cache keys. Use SHA-256 or SHA-512 when security matters.
- Yes. An empty input produces well-known empty digests for each algorithm — useful when debugging serializers or APIs.
- UTF-8 bytes, matching typical server-side hash implementations for Unicode strings. Emoji and non-Latin text hash the same way most Node and Python libraries do.
