[Feature Request] Add sum checksum

[rrooij]

Some checksum algorithms that are widely used are missing. Those are especially used on embedded devices with few resources.

To name a few:

• sum8
• sum16
• sum32

I've thought about adding them to wxHexEditor, but mhash doesn't support those. Should they be added to the mhash library or do they fit in a seperate .cpp file?

[EUA]

Well, I don't know mhash's internal structure.
I believe they can be implemented an external hash function but I am not planning to write them from scratch. Do you have any code that implement those?

[fenugrec]

I can probably help with some of this.
The original mhash proejct page seems pretty dead, is there a more recent fork somewhere ? It would make sense to add to upstream mhash, unless @EUA is using a heavily-modified version

Hi @fenugrec,
I looked similar projects but not find eligible one. Found Jacksum but unfortunately it's Java.
I don't make heavy modification to mhash. Just touched a bit for make it compileable on all OS'es.
