Description

spongycastle is currently used for two things:

  • elaborate KDF iteration calculation #2252
  • supporting Android < 2.3 (i.e. < android-9) #2182

The quick /proc/cpuinfo method in #3146 is much preferable to the elaborate KDF method, and there is probably not a big demand to support old APIs.

replace heavy KDF iteration count function with one based on /proc/cpuinfo

The previous KDF iteration count measuring method took a long time to run
and depended on including spongycastle. In the interest of keeping the
library as minimal as possible, it is good to remove dependencies. In the
interest of usability, calculating the iteration count should be very fast.
