From the developer:
EncryptedZip is dedicated to customers who are working with secure projects, and need to set a password for every Zip file before sharing it. The application allows you to set a "default password" and use it when compressing your valuable data. If you want to open or extract encrypted files with pre-set default password, you do not need to enter the password again.
