All in one offline Paperwallet generator

[LosPitufos]

Hi, I am searching around the forum for offline wallet generator, but I only find some posts about BitCoin.

I was wondering if there is a similar services for all the alt coins, and is there any difference in generating the wallet address, or do they use the same algorithm, only different prefix?

I would like to generate paper wallet for all my different currencies and keep the coins in there, as I do not want to install all the software wallets, as they take too much space and there is allays a risk of getting hacked.

IF anyone knows a good solution please feel free to help me.

Thanks for the fast replay.
I am wondering how will I know if the wallet created is for one or another alt coin?

I see that NMC starts with n or m, so in this place codes from 110 up to some of 114 will cover the prefix requirements, but not sure is they will work in the NMC network or each code represent a different coin and should be used for it.

Also It seems like I can not find the source to host it offline.
