Use conditions

The RAR, ZIP and WDZ formats do not protect the archive when it is opened. The password is required for extracting the files from the archive and for adding the files into the archive.
Archives in 7z format: This function is not available.
Archives in TAR and TGZ (TAR.GZ) format: This function is not available.

Reminder: Only ZIP, TAR and TGZ (TAR.GZ) archives are available.

Using an archive encrypted with a password

The password is defined by the function zipPassword. Once the password is defined, it is used for all the following archiving operations:

Adding files: the added files will be encrypted with this password
File extraction: the password will be used to decrypt all the extracted files.

The password is active for the archive on which it was defined. If the archive is destroyed (function zipClose), the password is lost. It must be specified again after zipOpen or zipCreate.

Miscellaneous

A different password can be specified for each added or extracted file in the same archive. You just have to use the zipPassword function each time you add or extract a file, specifying the password expected by the file to be added / extracted.
Unable to directly modify the password of a file found in an archive. You must extract the file, delete it from the archive and re-add it to the archive with the new password.
zipInfoFile is used to find out whether a file in the archive is encrypted (+) or normal (N).

Error codes

The following error codes are returned:
