Hash Generator (MD5, SHA)
Generate MD5, SHA-1, SHA-256 and SHA-512 hashes from any text.
About the Hash Generator (MD5, SHA)
Hash functions turn any input into a fixed-length fingerprint, used for checksums, data integrity, cache keys and (historically) password storage. The AlarmDaddy Hash Generator computes MD5, SHA-1, SHA-256 and SHA-512 hashes from any text, instantly and in your browser.
Type or paste your text and pick an algorithm. The hash updates as you type. MD5 and SHA-1 are fast and fine for checksums and cache keys but are cryptographically broken — never use them for security. SHA-256 and SHA-512 (computed via the browser's native Web Crypto) remain strong for integrity verification.
How to use this calculator
- 1Pick an algorithm: MD5, SHA-1, SHA-256, or SHA-512.
- 2Type or paste the text to hash.
- 3Read the hash, which updates as you type.
- 4Copy the hash with one click.
The formula
A hash function maps arbitrary input to a fixed-size output deterministically — the same input always yields the same hash, and any change to the input changes the hash completely. MD5 is computed in-page; the SHA family uses the browser's native Web Crypto API.
