MD5 Hash Generator

This MD5 hash generator can be used to encode passwords, credit card numbers and other sensitive data in MySQL, Postgress or other databases. PHP programmers, ASP programmers, and anyone developing with MySQL, SQL, Postgress, or similar tools should find this online tool a great handy resource.

What is an MD5 hash?

MD5 hashes are created by taking a string of arbitrary length and encoding it into a 128-bit fingerprint. Encoding the same string using the MD5 algorithm always produces the same 128-bit hash output. MD5 hashes are often used with smaller strings when storing passwords, credit card numbers, or other sensitive data in popular databases like MySQL. This tool provides a quick and easy way to encode MD5 hashes from simple strings up to 256 characters long.

MD5 hashes are also used to ensure the data integrity of files. Because the MD5 hashing algorithm always produces the same output for the same given input, the user can compare the hash of the source file with the hash of the newly created object file to verify that it is complete and unmodified.

MD5 hashing is not encryption. It's just the fingerprint of the given input. However, this is a one-way transaction, so it's nearly impossible to reverse engineer the MD5 hash to get the original string.
