ea3de7360c * Block versions don't have to be globally nondecreasing, but only per client id. This solves potential synchronization conflicts in a multi-client setting.
* Use cpputils::Serializer and cpputils::Deserializer instead of std::ifstream for storing/loading the block version list

d7f547dd47 Implement a VersionCountingBlockStore that checks that version numbers are nondecreasing. Currently, the block store is not used yet and the state is not stored over different runs of CryFS. This comes with future commits. 2016-06-26 22:15:52 -07:00

9ed7bd0b41 Ciphertext blocks are split into subdirectories (before, all were on top level) to reduce number of files per directory. Some unix tools don't work well with directories with too many entries. 2016-04-29 12:21:02 -07:00

037b59634e Implemented BlockStore::blockSizeFromPhysicalBlockSize. This will be used to let the user configure physical block size instead of virtual block size. 2016-03-16 18:56:06 +00:00
