Acerca de
A cryptographic hash turns any input into a fixed-length fingerprint. The same input always produces the same hash; even a one-character change produces a wildly different output. Hashes are used for file integrity checks, content addressing, signature schemes, and password storage (with the right algorithm).
This tool computes MD5, SHA-1, SHA-256, SHA-384, and SHA-512 in your browser using the Web Crypto API. Pick the algorithms you want, paste the input, and the digests appear instantly. For very large inputs, computation is asynchronous and the UI stays responsive.
Important: MD5 and SHA-1 are cryptographically broken — they should not be used for security purposes (signatures, password storage, integrity). They are still common for legacy checksums, deduplication, and content addressing, which is why we expose them. For new cryptographic work, use SHA-256 or stronger.
