[liberationtech] Cryptography super-group creates unbreakable encryption

Before the pad was ruined we also found out that:

- TiViPhone seems to be part of Silent Circle, (c) and all.. the lead
developers are listed on SC's founding page.
- Likewise the libraries notes, except PolarSSL, also seem to be develop
led by people now working for Silent Circle.
- Nadim admittingly jumped the gun on snprintf() issue
- We can't verify the libraries used or any of the code against the binary


So the skewering was premature. The pad, with other commentary, before it
was ruined is DLable at .. the revision
history slider still works but who knows how long as someone is mercilessly
trolling Nadim through it now. -Ali
