Description:
This directory contains open source code for modp base64 encode and decode
functions from https://github.com/client9/stringencoders.

Additional Notes:
Note that the directory structure in third_party/stringencoders mirrors that of
stringencoders-v3.10.3, therefore, the include files are placed in ./src
instead of ./include.

The following instructions demonstrate how modp_b64_data.h and modp_b64w_data.h
are generated. modp_b64_data.h and modp_b64w_data.h contain conversion tables
to generate standard base64 and web safe encoded base64 strings respectively.

For standard base64 files
  1. git clone https://github.com/client9/stringencoders.git
  2. cd stringencoders
  3. ./bootstrap.sh
  4. ./configure
  5. make
  6. make check
  7. now copy modp_b64_data.h to third_party/stringencoders/src/.
  8. copy src/modp_b64.c to third_party/stringencoders/src/*.cpp
  9. copy src/modp_b64.h to third_party/stringencoders/src/.

For web safe base64 files, repeat 1-9 above with the exception of
4, 7-9.
  4. ./configure --with-b64w-chars='-_='
  7. now copy modp_b64w_data.h to third_party/stringencoders/src/.
  8. copy src/modp_b64w.c to third_party/stringencoders/src/*.cpp
  9. copy src/modp_b64w.h to third_party/stringencoders/src/.
