The base 64 crap is the SHA256 of my MAC

In SM-G800F I can delete many things without full crashing...


So I delete ccm.dat knox.dat and folders...




So only this folder + file(s) left:
Code:
/efs/prov_data/dev_root

As i can write DRK via AT cmd... I "know" what is inside dev_root.dat...
Still I can NOT decrypt...


ccm_gen_cert create folder ccm + ccm.dat file...


After reboot knox and knox.dat is created... by "something"... no idea what...


Trustlet is not encrypted...


I can also play little bit with libcrypto.so ... less crash as less secured...
But...




I have libcrypto.so deleted IMHO in Android 5 and performed AT+DEVROOTK...
Successfully... so maybe not involved in this process...



But ccm_gen_cert for sure need proper libcrypto...


Otherwise this:
Code:
01-04 13:15:09.365 11411 11411 E FIPS_bssl: Entropy Initialization Failed : ccm_gen_cert  01-04 13:15:09.365 11411 11411 E FIPS_bssl: error:e83f708e:lib(232):func(1015):reason(142)  01-04 13:15:09.365 11411 11411 E FIPS_bssl: POST failed (0) reason (-1), invoking exit(EXIT_FAILURE) : [11411] ccm_gen_cert
