About MD5 Hash Generator — Free Online Tool
MD5 Hash Generator returns the 32-character hexadecimal MD5 digest of a string, in lower or upper case.
The string is encoded as UTF-8 and run through an MD5 implementation written into this page, because browsers deliberately leave MD5 out of their crypto APIs — it is treated as obsolete. That is the fact worth carrying away: MD5 collisions can be constructed on purpose, so it has no place near a password, a signature or anything else where someone has an incentive to forge a match. It remains the correct answer for a Gravatar URL, a cache key, or matching a checksum an older system published.
The digest is computed in the page, so the string being hashed is not transmitted — which matters when the string is an email address you are hashing for a Gravatar lookup.
Building a Gravatar avatar URL from an email address, generating a deterministic cache key, comparing against a legacy checksum, and reproducing a hash an older application stored.
Also known as: create md5 · md5 checksum maker · gravatar hash generator
When to use it
Calculate Gravatar email hash URLs, generate database cache keys, and verify legacy checksums.
How it works
Processes four 32-bit word buffers through four non-linear transformation rounds.
Security Note
MD5 is suitable for checksums and cache keys, but should NOT be used for password hashing.
