MD5 Hash
Instant 32/16-char MD5 digests from text
How to Use
MD5 is one of the most widely used hash algorithms, compressing any input into a fixed 128-bit digest (32 hex characters). The same input always yields the same output, making it useful for file-integrity checks, legacy password storage and API signatures.
How to use: type text and the 32-char lowercase MD5 appears automatically; toggle uppercase or take the middle 16 chars; click the result to copy. Everything is computed locally in your browser. Note that MD5 is collision-prone — avoid it in security-critical contexts.
FAQ
Can MD5 be decrypted?
No. MD5 is a one-way hash — the original text cannot be derived from the digest. So-called 'MD5 decryption' sites are rainbow-table lookups that only work for simple, common strings.
Is MD5 still secure?
MD5 is demonstrably vulnerable to collision attacks, so avoid it for digital signatures and certificates. It remains fine for checksums and deduplication. For security purposes use SHA-256 or stronger.
What is 16-char MD5?
It's the middle 16 characters (positions 9-24) of the standard 32-char digest — a shorthand still used by some legacy systems.
