I got this to work on Mac OS X - you have to install openssl from MacPorts, and then change the OBJS line in the Makefile to:
Code:
OBJS =   md5.o  utility.o  arch_crypto.o  archutil.o \
    aos_file.o /opt/local/lib/libssl.a /opt/local/lib/libcrypto.a

It should compile! It works fine for me (unpacking an .aos file)

archutil has been updated with new keys. It now includes keys for A705, A5IT, and all the keys for A53G+ minus the AES key. Same link as in the original post.


What can I do to retrieve the AES key for the A53G+ please ?

What is the restriction not to have this AES Key ?

(I have a segmentation fault when I try to archutil the Archos 3G+ firmware available here : http://update.archos.com/6/archos3gplus_sfr/archos3gplus_sfr_r1.5.10/firmware_archos3gplus_sfr.aos )

Thanks in advance !

Regards,

Get arbitrary code execution, dump flash. We've been discussing this on IRC for the last few days.
Another option would be to physically remove and read the flash chip. Something I would not recommend as there is no real benefit in doing so. Also the unit would be dead after this procedure.

Because nobody managed to dump the flash contents yet.

Yes that is because neither archutil nor aos-tools know the 3g+ FEK yet.

The encryption key is now known. I should be able to update archutil soon.

For Mac OS X compilation, i also had to add "/opt/local/lib/libz.a" to OBJS in Makefile:

Code:
OBJS =   md5.o  utility.o  arch_crypto.o  archutil.o \
    aos_file.o /opt/local/lib/libssl.a /opt/local/lib/libcrypto.a /opt/local/lib/libz.a

Question:
