Details

avm_dev_cert.cer is the AVM Device Certificate for this very model which is identified by its maca address.
It is issued by the AVM Device Manufacturer Root CA avm_dev_prod_ca.cer.
It comes with its own private key avm_dev_key_prv.bin, so it can be used to sign arbitary certificates.

This binary file is extracted from avmzertifikate to /var/tmp by libboxlib.so, to create the Box-Certificates.
After usage it is directly deleted, that's why it's unlikely to appear in Supportdata-Probes.
See the Model-Matrix of avmzertifikate to find out where it's used.

Box-Certificates:

• Temp: avm_dev_man_ca.cer, avm_dev_prod_ca.cer
• Temp: avm_dev_cert.cer, avm_dev_key_prv.bin
• Procfs: avmzertifikate, zertifikate, zertifikate2, zertifikate3, zertifikate4
• Procfs: prodcert1, prodcert2, prodcert3, prodcert4
• Sysfs: wlan_dect_config_part‎‎, wlan_dect_configs
• Kernel: prom_config.ko, prom_config_procfs.ko, avm_proc_calib.ko

Dependencies

Daily updated index of all dependencies of this temp file. Last update: 2024-11-14 07:04 GMT.
A * in the Mod column marks info from Supportdata-Probes, which will always stay incomplete.
A ** in the Mod column marks info from Supportdata2 probes, which by their nature will stay way more incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the item occurs, not the Relation.

Showing all models using this temp file. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list comes from Supportdata-Probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata file or just a disabled feature.
