+# wolfSSL for libnds
+
+## Requirements
+
+[Devkitpro](https://devkitpro.org/wiki/Getting_Started) with libnds.
+
+
+## Building
+
+```
+$ ./configure \
+ --host=arm-none-eabi \
+ CC=$DEVKITARM/bin/arm-none-eabi-g++ \
+ AR=$DEVKITARM/bin/arm-none-eabi-ar \
+ STRIP=$DEVKITARM/bin/arm-none-eabi-strip \
+ RANLIB=$DEVKITARM/bin/arm-none-eabi-ranlib \
+ LIBS="-lfat -lnds9" \
+ LDFLAGS="-L/opt/devkitpro/libnds/lib" \
+ --prefix=$DEVKITPRO/portlibs/nds \
+ CFLAGS="-march=armv5te -mtune=arm946e-s \
+ --specs=ds_arm9.specs -DARM9 -DNDS \
+ -DWOLFSSL_USER_IO \
+ -I$DEVKITPRO/libnds/include" \
+ --enable-fastmath --disable-benchmark \
+ --disable-shared --disable-examples --disable-ecc
+$ make
+$ sudo make install
+```
+
+## Run the Tests
+
+To run the Crypttests type the following.
+1. Run `$ ndstool -9 ./wolfcrypt/test/testwolfcrypt -c ./wolfcrypt/test/testwolfcrypt.nds`
+2. copy `./certs` to `your_nds_sd_card/_nds/certs`
+
+3. Run the Rom (located in ./wolfcrypt/test/testwolfcrypt.nds) in an Emulator or real Hardware.
