5651 Logs
What is it for?
The 5651 Logs screen lists the internet access records kept under Turkish Law No. 5651. Records are stored as daily files, a SHA-512 digest is taken of every file, and the nightly files are also sealed with a KamuSM qualified time stamp. This proves that a record was not changed later. When an official request arrives, you download the files to hand over from here.
When do I use it?
- A prosecutor, police or an authority such as BTK asks for the access records of a specific date.
- You want to check that records are signed regularly.
- You need to verify that a log file has not been changed.
- You want to see whether today's records, not yet signed, are flowing in (Active Log).
Before you start
- The list shows the selected device's records. If the device's internet address (IP) changed, records from the old address are listed too; a badge such as +1 eski IP (old IP) appears in the heading, and hovering over it shows the old address and the date it changed.
- For records to be created, 5651 logging must be on for the device (Device Settings). Keep the 5651 alerts on the Notifications screen turned on so you hear about signing problems.
- By law, records are kept for at least 2 years.
Step by step: downloading the record of a specific day
- In the left menu open Analytics and Reports and click 5651 Logs. The Signed Logs list opens; the heading shows the device's IP address and the number of files (example: 10.255.255.1 · Total: 3).
- Use the filters to find the requested date: pick from the Year and Month lists, or enter a day range with the Start and End calendars. The list is filtered as you choose. Clear removes all filters.
- Find the row that covers the requested time: the Log Period column shows from which time to which time the file holds records (example: 24-09-2026 01:00 → 25-09-2026 01:00); the grey text under it is the moment it was signed. Press the blue arrow (Günlüğü Kontrol Et, check log) at the end of the row.
- The 5651 Log Verification screen opens. The file name, signature type, signature date and file size are shown (the "Dosya" = File and "Dosya Boyutu" = File Size headings are still Turkish). Download the file with the down arrow (Download). The ZIP you get contains the log file (
.bz2), the digest file (.zmb) and, if present, the time stamp files (.zd,.ozet); hand the ZIP over as it is. The black box shows the file's signature details. To check that the file has not changed, press İmzayı Doğrula (verify signature); the result message appears on screen (see the message table below).
Step by step: checking that today's records are flowing
- Press the yellow Active Log button above the list.
- The 5651 İmza Durumu (signature status) screen, shown in Turkish only, has an Aktif 5651 Günlüğü (active 5651 log) table with today's file that is not signed yet: Dosya (file), Dosya Boyutu (file size) and Log Sayısı (number of log lines). The latest record lines scroll in the black box below; the screen refreshes itself every 5 seconds. If the size and the log count grow, logging works. If you see 0 bytes, no records are coming from the device; tell the company that installed it or support.

Frequently asked questions
Why does a file run from one night to the next?
Records are closed and signed at a set time every night. So a file usually holds the records from the previous night's time to that night's time.
Are the records of employees on the Excluded Users list here too?
Yes. 5651 records are kept in full for everyone; that list only affects guest reports.
