Depends what you mean by 'password-protected'. There's at least three different kinds of password-protection supported in the .zip format: the old obfuscation system that dates back to the MS-DOS days and pkzip 2.04g, the AES-based system introduced with WinZip 11, and the similar-but-incompatible AES-based system introduced by PKWare at about the same time.
So far as I know, pretty much every .zip tool supports the old obfuscation system which can be brute-forced fairly easily (especially on modern hardware). I believe only the latest Windows versions of WinZip and PKZip support their respective versions of AES-encryption, and probably not each others'.
