Code:
gzip -c infile.gz > outfile.gz.gz

ZIP_SET_DEFAULT_PASSWORD(3)				     Library Functions Manual				       ZIP_SET_DEFAULT_PASSWORD(3)

NAME
zip_set_default_password - set default password for encrypted files in zip LIBRARY
libzip (-lzip) SYNOPSIS
#include <zip.h> int zip_set_default_password(struct zip *archive, const char *password); DESCRIPTION
The zip_set_default_password function sets the default password used when accessing encrypted files. If password is NULL, the default password is unset. If you prefer a different password for single files, use zip_fopen_encrypted(3) instead of zip_fopen(3). Usually, however, the same pass- word is used for every file in an zip archive. RETURN VALUES
Upon successful completion 0 is returned. Otherwise, -1 is returned and the error information in archive is set to indicate the error. ERRORS
zip_set_default_password fails if: [ZIP_ER_MEMORY] Required memory could not be allocated. SEE ALSO
libzip(3), zip_fopen(3), zip_fopen_encrypted(3) AUTHORS
