OSDP Capture Analyzer

Upload a capture from any OSDP tool that records traffic in the .osdpcap format, such as the OSDP.Net ACU and PD Consoles or OSDP Bench. It's decoded with OSDP.Net, checked for protocol problems, and reviewed by Claude against the OSDP 2.2.2 specification.

The analyzer needs JavaScript and a free Z-bit account.

Choose an .osdpcap file, or drop it here Up to 25 MB. The ACU and PD Consoles save captures in the captures folder beside the app. What should Claude look at? Optional

Secure Channel and privacy options

Secure Channel key (SCBK) Only needed if the device doesn't use the default key Used on our server to decrypt the capture. It is never sent to Claude or stored. Include card numbers and keypad digits Off by default: card bits, keypad digits, biometric data and keys are replaced with [masked] before anything leaves our server. Bit counts and formats are kept.

Your capture is decoded on our server, and the decoded summary is sent to Anthropic's Claude for analysis. We don't keep the capture; the conversation is held in memory for an hour so you can ask follow-up questions. AI analysis can be wrong, so check its findings against the specification. See the privacy policy.

How it works

Decode

OSDP.Net decodes every packet the way the test consoles do, and decrypts Secure Channel traffic with the default key or the key you give.

Check

Every record is checked for bad CRCs and MACs, NAKs, missing or slow replies, sequence errors and silences. Routine polling is condensed, so long captures fit.

Review

Claude Haiku reads the decoded capture with the OSDP 2.2.2 specification at hand, then explains what it finds and what to try next. Ask follow-up questions about the same capture.
