[ANNOUNCE] eCL0WN for Android v1.0 released

I'm pleased to *finally* announce the release of eCL0WN for Android v1.0.

eCL0WN is an Android ePassport utility for NFC-enabled phones that allows you to read and clone your ePassport's chip 
content. The following functionality is implemented in the current release:

- Read passport data using a given authentication key (if needed).
- View passport details including the JPEG picture.
- Write passport data to an emulator chip.
- Write passport data to internal storage (not very secure).

Supported devices
eCL0WN requires an NFC-enabled phone running Android 2.3+.

eCL0WN reads ePassport files EF.COM, EF.SOD, EF.DG1 and EF.DG2. If present, the optional files EF.DG7, EF.DG11, 
EF.DG12, EF.DG13 and EF.DG15 will also be read. Retrieved data can be written to an ePassport emulator. Use Dexlab's 
epassport_emulator-v1.02 (or higher) as the target device. You need a JCOP card and a PC to prepare the emulator. 
Please refer to <http://dexlab.nl/downloads.html#emulator> for more details. Before writing files to the emulator all 
Active Authentication (AA) related, Extended Access Control (EAC) related and unknown files (if any) are  removed from 
index EF.COM. This allows one to bypass AA and EAC checks of inspection systems vulnerable to downgrade-attacks.

Note that eCL0WN does not comply with ICAO Doc 9303 at all. Please do not use it to check authenticity or integrity of 
machine readable travel documents.

Known problems
ePassport chips typically comply with the ISO/IEC 14443 A or B standard. The A standard is widely used in at least 
Western Europe and the US. The B standard is widely used in at least Asia. Antenna quality of some NFC-enabled Android 
devices is very poor (e.g. the Google Nexus S). If this is the case for your phone you won't be able to communicate 
with ISO/IEC 14443 type B ePassport chips. This is NOT an eCL0WN bug, this is a hardware problem.
