Zefer : Generate multiple serial codes on your computer that you can use to protect your application by turning to this lightweight utility

In depth

A closer look at Zefer

If you are working as a software developer, you probably understand the importance of protecting your projects by any means possible.Since nowadays serial keys are one of the most used security methods, a serial number generator might come in handy if you want to create a database of valid keys. One of the applications that can help you do that is Zefer.

Quick setup

This program can be easily installed on your computer since it does not require you to perform any complicated configuration steps during its setup.You just need to specify your desired destination path, decide whether desktop or start menu shortcuts should be created or not and follow the on-screen instructions.

Plain layout

Zefer packs a simple, visually unappealing user interface, which encompasses a couple of functions that are relevant to its purpose. This makes it possible for a broad range of users to benefit from its capabilities without significant efforts, despite their PC skills.However, despite its simplicity, it also features a handy user guide that can help you understand and operate its controls in a more efficient manner.

Generate serial numbers

You can turn to this tool if you need a quick way to generate serial numbers on your computer. On the downside, it is only possible to create numeric serials, since alphabetic characters are not supported. This utility's main window features two buttons, one for generating a single string and the other one for creating multiple ones.It is possible to modify the number of keys by typing it in the designated field.

Exports the generated strings, one by one

Additionally, you can choose to save the generated serial numbers by exporting them to your computer as text files. However, instead of collecting all of the resulting keys and placing them in the same file, this utility prompts you to save the strings individually, in different documents.

Simple numeric serial key generator with no output file support

All in all, Zefer is a lightweight application that can help you generate multiple serial keys on your computer, although, unfortunately, only numeric characters are supported. It packs a plain user interface that encompasses a couple of buttons and can save your serial numbers on your computer. However, it is only possible to save one string at a time.
