It's written in Purebasic - and this language also supports linux (but I've never tried to compile something for linux... so I don't know how easy it will be). |

weird Q, do you know how to handle bus encryption? In that case my ddrescue method would probably need to be implemented in place of whatever tool is doing the "bus decryption" unless its possible to authenticate to the drive and then reads just work as expected? (don't know enough about bus encryption obviously)

Bus encryption is handled by libaacs if you have a working host certificate (which we have). Pretty nice description is available on libaacs git: http://git.videolan.org/?p=libaacs.g...e8912684fb7b9d
Most discs do not implement bus encryption anyway, so it probably is not really a big problem. |

ok, what that means to me is that my ddrescue type method to recover damaged disks will not work with a bus encrypted disc.
I was hoping it was more along the lines if you cryptographically authenticate to the player/drive/disc than any read will be unencrypted otherwise the drive will encrypt/mangle it, but guess that's not the case and that it's actually a generation of a "dynamic" key that is used to encrypt (in drive) and decrypt (in player) the data. my current ddrescue methodology is essentially ddresccue -> iso (repeat until one gets it 100% might require multiple media copies, but all can be damaged) BlurayTestAndDecrypt -> decrypted iso (and I'm trying to see how dvdfab/anydvd act on a encrypted and decrypted iso, would they decrypt an iso, would they remove the "structural" (i.e. non crypto) protections from a decrypted iso) I guess its good that not many discs use it then. |

1) There appears to be a problem with non-encrypted m2ts file in mode 3/4 (mode 2 works fine)

I'll promise that I've never and will never integrate harmful procedures into my tools - but finally it's up to you if you want to trust me or not. |

Should be possible - but need to finish the other work before I'll start to implement this one. |

Released a new build - it fixes the problem reported by candela and also introduces the ability to decrypt files with mediakey+volumeid or unitkeys from keydb.cfg file.
But I have to admit that I haven't tested this feature... so please keep me posted if it's working as expected I've changed the logging procedure and splitted the source into lot's of smaller modules and it's possible to set the loglevel for each module as you want. There's a new entry in the ini file called 'LogLevel' and usually only a 'Default' entry is present and set to level 2='INFO' Logentries look like: Code:
2017-01-05 22:28:20 # 13865088 # [I] bluray_udf / _UDF_Parse_FileSystem / date+time - milliseconds - loglevel - module - procedure - logentry so in case you want for example less logoutput for the 'bluray_udf' module, simply add a line 'bluray_udf=1' into the loglevel ini section and now only errors and warnings are logged. I made a few simply tests and I think it should work In case of errors just come back to me and I'll try to fix them. |

Some basic test shows the unencrypted m2ts bug is fixed and it works with only a unitkey.
Btw, if a unitkey is missing (eg multiple unitkeys required but only 1 known) you get an error but the file isn't copied. Perhaps there should be an option to copy the file encrypted. Then the encryption can still be removed later if a "better" key is found Last edited by candela; 6th January 2017 at 01:59. |

I was wondering because I have no AntiVirus software installed. And I have never seen before a virus warning directly from Waterfox. |
