I need a tool to generate and maintain the checksum (MD5, SHA1, it does not matter) of all files in a folder or a set of folders, recursively.
Sometimes I will add/update/remove some files and I would like to not recalculate the checksum of the old files.
So, these are the requirements:
- generate the first time the checksum of all files.
- generate incrementally the checksum of the added/updated/removed files.
- verify the checksum of the files.
Does anybody know such a tool?
Thanks in advance.
