Free MD5, SHA-1, SHA-256 & SHA-512 Hash Generator
Generate cryptographic hashes from any text in your browser. Get MD5, SHA-1, SHA-256, and SHA-512 digests instantly — useful for checksums, integrity verification, and development workflows.
Hash functions take an input of any length and produce a fixed-length fingerprint. Even a one-character change in the input produces a completely different hash, which makes hashes ideal for verifying data integrity or comparing values without exposing the original.
MD5 and SHA-1 are fast but no longer considered secure for cryptographic purposes — use SHA-256 or SHA-512 for security-sensitive work. All computation happens locally using the Web Crypto API; your text never leaves the browser.
Frequently Asked Questions
Are these hashes secure?
SHA-256 and SHA-512 are secure. MD5 and SHA-1 are suitable only for non-security uses like checksums.
Which API is used?
SHA variants use the browser's Web Crypto API; MD5 uses a pure-JS implementation since Web Crypto doesn't include it.
Does it support Unicode?
Yes — input is encoded as UTF-8 before hashing.
Is my text uploaded?
No. Everything runs entirely in your browser.
