Answer the question
In order to leave comments, you need to log in
If the length of the key is equal to the size of the archive, then you will not decrypt it so easily. If it is much less, say, 8-100 bytes, then you can try.
To begin with, take the known bytes of the zip archive (header, long sequences of zeros, etc., compare with any unencrypted archive) and proxy to the corresponding bytes of the encrypted one. Now you know part of the key. If the key is some kind of phrase, you can guess or pick up the missing bytes. Otherwise, if the key length is known, you can proxy the archive to the known bytes of the key, try to guess the neighboring bytes from the decrypted bytes, get new bytes thanks to them, and start over.
Something like this.
