Details

libaseceng.so is an optional ASEC device certificate plugin lib for libavmssl.so. AVM calls it ASEC engine for OpenSSL.
libboxlib.so and supportdata check for the presence of this optional library. Only libavmssl.so opens it.

Examples

Excerpt from supportdata fw 7.39:

echo "##### BEGIN SECTION device certificate"

if [ -e /proc/avm/calib/avmzertifikate ] ; then
    ls -l /proc/avm/calib/avmzertifikate
    /bin/gzip -c -d /proc/avm/calib/avmzertifikate | /bin/tar t -v -f -
else
    echo file /proc/avm/calib/avmzertifikate does not exist
fi

if [ -e /usr/lib/libaseceng.so ] ; then
    ls -l /usr/lib/libaseceng.so
else
    echo file /usr/lib/libaseceng.so does not exist
fi

echo "##### END SECTION device certificate"

Sample output of 7530ac fw 7.39 supportdata where both do not exist:

##### BEGIN SECTION device certificate

file /proc/avm/calib/avmzertifikate does not exist
file /usr/lib/libaseceng.so does not exist

##### END SECTION device certificate

Sample output of 7520 fw 7.39 supportdata where both exists:

##### BEGIN SECTION device certificate

-rwxrwxrwx 0/0       873 2019-07-25 00:21:03 avm_dev_cert.cer
-rwxrwxrwx 0/0      1217 2019-07-25 00:21:03 avm_dev_key_prv.bin
-rwxrwxrwx 0/0      1013 2019-07-25 00:21:02 avm_dev_man_ca.cer
-rwxrwxrwx 0/0       780 2019-07-25 00:21:02 avm_dev_prod_ca.cer
-rw-r--r--    1 root     root        249788 Apr  8 11:12 /usr/lib/libaseceng.so

##### END SECTION device certificate

This is faked, since there is no 7520 7.39 labor yet, but a freetz 7530ac labor alien.

CrossRef

A cross reference shows where functions of a library are used in the system, very helpful to find out the purpose of a library.
fw 7.39 function cross reference:

Functions:

• only used in libavmssl.so:
  • aseceng_init
  • aseceng_load_key, aseceng_load_key_group
• not used elsewhere:
  • aseceng_finish
  • aseceng_rsa_makekey
  • asecengine_ERR_error, asecengine_ERR_load_strings, asecengine_ERR_unload_strings
  • bind_engine
  • gunzip_file
  • init_rsa
  • load_boxkey
  • v_check

Source

The names of source files compiled into an executable often help to understand function blocks (and show gaps in the docs).
