MD5 signatures are 32 hex digit strings derived from (binary) files by a highly specific algorithm. Files that differ only slightly have completely different signatures. Also, it is really extremely unlikely that two different files have the same signatures.
MD5 signatures can therefore be useful to verify the integrity of files e.g. after copying. The two utilities presented here enable you to make and check signatures in an easy and quick way.

This pack contains the latest updates. They have been tested for Windows Vista, XP, 2000 and 98. Installing a newer version is automatically preceded by an uninstall procedure.

The MD5Maker can be started from the Explorer´s context menu when you right-click on a selection. MD5 signatures of ALL the files in this selection - including the files in its directories and subdirectories - are calculated and stored in the MD5 Signature File.

The MD5Verify program has the MD5 extension associated to the program. This makes starting the program possible by double-clicking on an MD5 Signature File. All signatures are checked against the corresponding files. Both programs support drag and drop.
