When I try to compile a platformio project that uses ota update and ArduinoJWT on esp8266 I get an error in ESP8266HTTPClient which uses its own implementation of base64.
compilation error below:

Solution:
Download attached ZIP with new library.
ArduinoJWT.zip
Explanation:
Edit ArduinoJWT and modify line 37:
const char* jwtHeader PROGMEM= "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9";
to:
const char* const jwtHeader PROGMEM= "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9";
Then in sha256.cpp you have to edit the original adding const to "unsigned char sha256InitState[] PROGMEM" and "uint32_t sha256K[] PROGMEM"
So ends like:
const uint32_t sha256K[] PROGMEM = {
0x428a2f98,0x71374491,0xb5c0fbcf,0xe9b5dba5,0x3956c25b,0x59f111f1,0x923f82a4,0xab1c5ed5,

Google iot core only support RS256 JWT.
do you have any plan or road map to support RS256. Very Thanks.
You list platforms as atmelavr
and espressif
, but it works fine on esp32 (where I've been using it for quite a while, alongside esp8266).
For one of my projects I've now had to switch to lib_compat_mode = strict
because I have another library dependency that only support esp32 and not esp8266, but the side effect is that ArduinoJWT is no longer included because it doesn't list esp32 among the supported platforms.
Hi,
I am trying to use your Library, and when I try to add library through Arduino IDE/Library Manager, I get the following error:
"Invalid Library Found in Documents/Arduino/libraries/ArduinoJWT-master"
Can you help me with this issue?
Thanks,
Shab
As there is no exampleof implementation here I leave a small arduino sketch, hope it can help you:
#include <ArduinoJWT.h>
#include <sha256.h>
ArduinoJWT jwt = ArduinoJWT("secret");
void setup() {
Serial.begin(9600);
// jwt.setPSK("My secret");
String msg = [];
msg["Monto"]=
Serial.println(jwt.encodeJWT(msg));
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
I want use this library to encode information in arduino uno and send it to the web server , can you help me ? ( I want an example code for encoding )
Have Arduino UNO but can't make it run.
Have implemented some fixes for variable type, but lib itself return NULL value.
Is any suggestion/example how to use lib ?
