MD5 Hash Generator
Generate MD5 hashes from text, hex or Base64 input, hash each line separately, and get the result as lowercase, uppercase or Base64. Runs entirely in your browser.
MD5 turns any input into a fixed 128-bit fingerprint, written as 32 hex characters. This generator hashes text, raw hex bytes or Base64, can process each line on its own, and outputs hex or Base64. It all runs in your browser, so nothing is sent anywhere.
How to use this tool
- Paste your input.
- Tell the tool whether it is text, hex or Base64.
- Optionally hash each line separately for a table.
- Copy the hash in the format you need.
Formula
MD5 processes the message in 512-bit blocks through four rounds of bitwise operations, producing a 128-bit digest. The same input always gives the same hash; the smallest change gives a completely different one.
MD5 is a one-way hash: you cannot reverse it to recover the input.
Example
MD5 of "abc" is 900150983cd24fb0d6963f7d28e17f72, and MD5 of the empty string is d41d8cd98f00b204e9800998ecf8427e — both from the RFC 1321 test vectors.
Frequently asked questions
Is MD5 safe for passwords or security?
No. MD5 is fast and has known collision attacks, so it must not be used for passwords, signatures or security. Use it only for checksums and non-security fingerprints; for passwords use bcrypt or Argon2.
Can MD5 be decrypted?
No. MD5 is not encryption and has no key — it cannot be reversed. A "decrypter" only looks a hash up in a table of previously hashed common strings.
Why hash each line?
It is handy for fingerprinting a list of values at once, such as checking many short strings against known hashes.
