## This file contains a record of how some of the test data was
## generated. The final build products are committed to the repository
## as well to make sure that the test data is identical. You do not
## need to use this makefile unless you're extending mbed TLS's tests.

## Many data files were generated prior to the existence of this
## makefile, so the method of their generation was not recorded.

## Note that in addition to depending on the version of the data
## generation tool, many of the build outputs are randomized, so
## running this makefile twice would not produce the same results.

## Tools
OPENSSL ?= openssl
FAKETIME ?= faketime

## Build the generated test data. Note that since the final outputs
## are committed to the repository, this target should do nothing on a
## fresh checkout. Furthermore, since the generation is randomized,
## re-running the same targets may result in differing files. The goal
## of this makefile is primarily to serve as a record of how the
## targets were generated in the first place.
