JSON to Java Class
Generate Java POJOs or records with Jackson annotations from JSON.
Generate an MD5 hash of any text, with a straight answer about when not to.
MD5 is broken for anything security-related. Use it for cache keys and corruption checks; use bcrypt for passwords and SHA-256 for integrity.
The MD5 Generator produces a 128-bit digest of any text as 32 hexadecimal digits, with full Unicode handling and a compare box — plus a straight account of where MD5 is still fine and where it is badly broken.
MD5 turns any input into a 128-bit fingerprint written as 32 hexadecimal digits. Change one character of the input and the whole digest changes, which is what makes it useful for spotting accidental corruption and for cheap cache keys and deduplication.
It is broken for anything security-related, and the tool says so rather than pretending otherwise. Collisions — two different inputs with the same digest — can be produced in seconds on a laptop, so MD5 must not be used for password storage, signatures, or verifying that a download has not been tampered with by someone who wanted to tamper with it. For those, use bcrypt for passwords and SHA-256 for integrity. For a cache key or an ETag, MD5 is fine and fast.
MD5 collides in seconds on a laptop, so the page says plainly where it must not be used rather than presenting it as a security tool.
Text is UTF-8 encoded before hashing, so an accented character or an emoji gives the same digest as any other correct implementation.
Paste an expected digest and the tool confirms whether it matches, instead of you reading 32 characters by eye.
The digest updates on every keystroke, which makes it obvious how completely one changed character rewrites the output.
The hash is computed in your browser, so payloads and identifiers are not transmitted anywhere.
Anything — a string, a payload, a file's contents as text.
The 32-character hash appears as you type, in upper or lower case.
Paste an expected hash to check the two match without reading them character by character.
One click puts the digest on your clipboard.
No. Collisions can be generated in seconds, so it must not be used for passwords, signatures or tamper detection. It is still fine for cache keys, deduplication and catching accidental corruption.
Not mathematically, but for short or common inputs it does not need to be — rainbow tables have the answer already. Treat any MD5 of a password as effectively public.
bcrypt or Argon2 for passwords, SHA-256 for file integrity, and HMAC-SHA256 when you need to prove a message came from someone holding a key.
Almost always a trailing newline or a different character encoding. This tool hashes exactly the bytes you paste, UTF-8 encoded, with nothing added.
