2e7479525f turned crypto_secretbox nonces into counters, thereby implementing counter mode (CTR mode). we use variable size counters, max counter size is 184 bit, max implemented currently are 64 bit, multiply by 32kb and you get the maximum file size supported by pcp encryption 2015-01-16 00:13:02 +01:00

26d4ee43c5 started to implement pbp compatibility, added support for multiple -r options, 
using it now to look through the vault for recipients, -i to follow. current
state: encrypt produces output without errors or crashes; decrypt is incompatible
for the moment.

67ba04f3bd moved file en/de-cryption from src to libpcp, which makes it way easier to 
implement pbp compatibility
