First-Of-A-Kind and The Only

Full Stack WYSIWYG Pcap Editor

Edit L2 - L7 with just a few clicks



Simple Interface

Edit a network packet at any stack layer from L2 to L7 with just a few keystrokes. No hacking required.

Deep Understanding

WireEdit knows all elements of a packet, their types, encoding, inter-dependency, position offsets, constraints, checksums, etc.

Just works

As you're editing WireEdit takes care of all the behind-the-scene details on-the-fly. No need to think about any of it.

Frequently Asked Questions

What is WireEdit?

WireEdit is first-of-a-kind and the only full stack cross-platform WYSIWYG network packets editor. It allows editing packets data at all stack layers as "rich text" in a simple point-and-click interface. The input and output format is Pcap.

What if one has to quickly edit some upper layers fields and add/delete some optional fields in captured packets, all on the condition that it's impossible to tell whether or not any editing has been done? WireEdit solves this problem.

WireEdit is similar to what?

We are not aware of a comparable full stack packet editor, free or commercial.

Is WireEdit a Pcap Editor?

Yes, but it's just a small fraction of its capabilities. WireEdit at its core is about editing the packets' data itself, including the application stack layers above TCP/UDP/SCTP.

Strictly speaking, Pcap is just a wrapper format for holding captured packets binaries. While some Pcap metadata (timestamps for example) editing is supported by WireEdit for user convenience, it's generally not the main focus of the development. A good list of existing Pcap tools could be found here.

Use case example?

Network packets carry all kinds of sensitive data, including login credentials, crypto keys, private text messages, etc. In fact, data carried by any packet field can be considered sensitive in some context. How could one quickly scrub the sensitive data from a pcap file, while keeping the structure and integrity of the packets binaries otherwise intact?

You need a full stack packet editor. WireEdit is the only one.

Is WireEdit open source?


What platforms are supported?

Win10, Ubuntu Desktop 16.04/18.04, Mac OSX.

What protocols/layers are supported?

A lot. Adding new stacks/protocols monthly. Download the latest WireEdit build and see for yourself.

What's so special about this?

In order to edit a text document one doesn't have to know about the character encoding schemes, formatting and pagination algorithms, etc. To use a vector graphics editor one doesn't have to know vector math. In these and many other cases visual editors take care of the hard stuff behind-the-scenes.

WireEdit allows editing network packets at any stack layer without knowing their syntax and the encoding rules. You can edit packets in WYSIWYG mode without directly manipulating their binaries. WireEdit verifies all the changes you make on-the-fly and takes care of fields/layers encoding, offsets, inter-dependency, integrity, etc.

Does WireEdit support packet scrubbing?

Yes. You can perform bulk overwrite of sensitive packet fields in Layers 2-7 for without breaking the packets binary structure.

What about the checksums?

Any packet field which can be calculated according to specs is calculated on-the-fly. No user action is required.

Can protocol X be supported?

Yes. WireEdit can support any network protocol/stack no matter how complex.

Can I modify packets binary data directly?

Yes. Moreover, you can edit as Hex a selected stack layer (a PDU) or even a single data field. You can switch back to WYSIWYG mode at any moment.

Can I add support for stack Y myself?

No, but we would be happy to talk about it.

Can I do packet fuzzing?

Yes. You have to use special Field Overwrite mode. In this mode you can break the syntax rules, but then you're on your own.
