Build SMB packets from structured fields
Use this SMB packet generator to compose binary fields, text values, and application payloads from structured values. The generated bytes can be copied as Hex or Base64, downloaded as BIN, and sent to the SMB parser for verification.
01Choose a SMB message profile when a template is available, or switch to Field sequence to arrange typed values manually.
02Numeric fields support explicit byte order where applicable; text, Hex, and Base64 fields preserve the exact bytes you enter.
03Generated output is intended for protocol tests, parser fixtures, interoperability checks, and controlled packet analysis.
Frequently asked questions
What can I generate for SMB?
You can compose binary fields, text values, and application payloads with the available SMB profile fields, then export the resulting application-layer bytes as Hex, Base64, or a binary file.
Can I verify the generated SMB packet?
Yes. Use Verify in parser to open the matching SMB parser with the generated bytes preloaded.
