Probably far from the best option; but you could use 7zip? Put a 7zip portable exe & linux binary on the usb, put the regular contents in an encrypted .zip file, anyone with the password can decrypt. I assume there are much more secure options though.
Encrypted ZIPs are very trivial to break. I can break it with a simple python script.
For instance, Microsoft does that for all encrypted ZIPs

ZIP isn't a good way to encrypt, but what Microsoft is doing is simply reading the email, and decrypting zips with the password found in the email body.
All encryptions schemes can be trivially broken if you have the key. It's not even breaking, it's just normal decryption.
No, zip encryption is very weak. Thus is because million of combinations can be tried very quickly
While that's true, but there's no indication of Microsoft brute forcing with million of combinations.
The article you link says Microsoft is only trying a few obvious passwords: the filename, and words found in the plaintext message.
Proper encryption isn't just about using a strong algorithm. It's also about proper key management, ie not sending the password in the clear via the same channel as the encrypted files.
Well no ZIP is not secure. There is a plethora of software that can brute force it.
Do not trust zip encryption. It is not secure and it will likely never be secure. It is like storing your passwords on a spreadsheet
7zip encryption is solid, but the problem with this is that you don't Mount 7zip, so you have to extract it. Once you extract encrypted files into a drive thats not encrypted, they may as well never have been encrypted in the first place.
Its better to use a tool that creates an encrypted filesystem that you can mount and read-write directly without copying the files onto another disk
