Dear monks,

I got a hash which ususally gets few or even no keys. It is given to some external module which may change it.

I'ld like to keep a copy before handing the hash to the external function and compare hash and copy after the function returns to detect if there are changes.

I'ld like to advoid writing a TIE-module for this.

Is there a module which creates a hash checksum? I searched CPAN but had no luck.

Thank you.
