MD5 Generator
What is MD5? (Message-Digest algorithm 5)
This is a very popular cryptographic hash function with a 128-bit hash value.
It's frequently used to:
- check the integrity of files - file owners sometimes provide an MD5 checksum, so that a user can compare the checksum of the downloaded file to it,
- compare files and long texts - this is a very fast solution if you want to check if one text or file is the same as other text or file,
- create digital signatures,
- store passwords.
Because of weaknesses of the md5 hash function you should use other algorithms, such as SHA-1 or algorithms from SHA-2 family (for example SHA-512).
This hash function was designed by Professor Ronald Rivest in 1991. Find out more about this algorithm.
MD5 Hash
An MD5 hash (such as MD4 and MD2) is typically expressed as a 32 digit hexadecimal number. The md5 generator converts a string into an md5 hash value. For example, if you type "password" in the input field above and submit you get a digit: 5f4dcc3b5aa765d61d8327deb882cf99. The digit is your hash.
MD4 and MD2
MD4 is a predecessor of the MD5. At present MD4 is useless because collisions can be generated in a few seconds on a common PC.
MD2 was developed in 1989. The algorithm was optimized for 8-bit computers.
