To zip with password in command line

zip -P PASSWORD zipfile.zip BigSecureFile.txt

To unzip, enter the password when prompted

unzip zipfile.zip

You have been warned!

   -P password
   --password password
          Use password to encrypt zipfile entries (if any).  THIS IS INSECURE!  Many multi-user operating systems provide ways for any
          user to see the current command line of any other user; even on stand-alone systems there is always the threat of  over-the-
          shoulder  peeking.  Storing the plaintext password as part of a command line in an automated script is even worse.  Whenever
          possible, use the non-echoing, interactive prompt to enter passwords.  (And where security is truly  important,  use  strong
          encryption such as Pretty Good Privacy instead of the relatively weak standard encryption provided by zipfile utilities.)
