base64_decode() issue

[boria8]

i'm getting segfault on conversion of "MA==" base64 string to Opaque from utils_base64ToOpaque function in the following line:
*bufferP[result_index - 3] = (tmp[0] << 2) | (tmp[1] >> 4);

Yes, this implementation is bugged.
I am considering removing it as it is not used currently in wakaama and it is not exposed.

[boria8]

actually i think that such api is required(#273 ), i'm not sure that the best way is to implement it from scratch.

[dnav]

In #271 I moved the base64 decode function to examples/shared/commandline.c until we figure something adressing #273.

[dnav]

utils_base64ToOpaque() is now base64_decode() and part of examples/shared

[boria8]

Is there a plan to fix this api?

[dnav]

Personnaly, like every other issues tagged examples, it is pretty low on my TODO list.
base64 is very common so it should be easy to replace the code with a working version.

I think this is resolved by utils_base64Decode introduced in #428.

It should be fixed.
(should if be backported in a 1.x version ? #487)
