Online JavaScript MD5 Line-by-Line Hasher


I needed a script to generate MD5 hash values of multiple cells in an Excel spreadsheet. So, for example, imagine you have Column A which contains employee ids, and you want to hash these.

I put together a simple javascript page to do just this. Simply click on the link, copy all of Column A into the top textarea, enter a salt or password (or leave blank for none), and click Generate MD5 Hashes.

The hash values will appear in the textarea at the bottom of the page.

Note that all leading and trailing spaces are removed from all field values and from the salt. So if leading/trailing spaces are important to you, you may need to hack the source to prevent the trim functions being called.
