Open source tools to convert uncommon private keys

[1miau]

I'm searching open source tools to convert uncommon Bitcoin private keys to different formats.
For example Mini private keys, as contained in original Casascius coins. 
A recent request was posted here in our German section: Physischen Bitcoin digitalisieren (Digitalize physical Bitcoin)

So far, I only know Bitaddress.org from Pointbiz, can be downloaded here and run offline (https://github.com/pointbiz/bitaddress.org/releases)



Do you know more beginner-friendly open-source tools like Bitaddress.org from Pointbiz?
Looking forward to your responses.

https://github.com/Kimbatt/btc-address-generator might do the same thing.
Other alternatives are either scams or their developers have stopped updating.

I never even knew that there were different private keys format until I came across an RSA format from mycelium.
I used this in changing mine https://bitcoin-key-compression.com/ got it from their github here.

I'm not sure the OP is asking for a tool in generating addresses or maybe it's a multipurpose tools.

This works for private keys WIF that start from 6P, K or L. It does not work for the WIF that starts from 5. It does not work with mini private keys. The tool does not also show the details of other private keys.

You could use the Bitcoin address utility used by Casascius (Caldwell). Does not exist anywhere but you could use internet archives to download the source code.

Before anything, is important to remember there is a huge risk each time you put your privatekey on any site, so, be careful about it, that way you are compromising your Keys, and isn't a smart move at all.

Now, i would like to recommend this service for learning purposes. https://secretscan.org/PrivateKeyHex

That site not only lets us convert any kind of private key to the address, it gives us the value from each step of the conversion, and that is awesome. But never use a personal private key for it, that would be a big mistake.

You can download Mike Caldwell's code supporting mini keys here: https://github.com/casascius/Bitcoin-Address-Utility

Many thanks for all of your recommendation here, your advice is much appreciated. 
If I can find some time next weekend, I'll try to check all of your recommendations in my topic so far to see which one is coming closest to what's an optimal solution.
It seems like a converter of Mini private keys seems to be a frequently asked quation because at least in our German section, wh had someone asking about Mini private keys earlier as well.
