can't create token - 'NotImplementedError: Unsupported signing method' #186

Jpease1020 · 2017-01-31T16:41:12Z

when I run this code,

payload = 'username'
hmac_secret = 'my$ecretK3y'
token = JWT.encode payload, hmac_secret, 'HS256'

I get this error JSON::GeneratorError: only generation of JSON objects or arrays allowed

I am using ruby version 2.3.0 in a rails 4.2.6 project

Your payload needs to be a hash.

payload = {
    username: 'username'
}

I changed the payload to

payload = { username: 'username' }

and ran

payload = { username: 'username' }
hmac_secret = 'my$ecretK3y'
JWT.encode(payload, hmac_secret, "H256")

and I get this error

NotImplementedError: Unsupported signing method

@Jpease1020 Were you able to solve this? I am having same issue!

@HimaChitalia

Have you checked for typos? Sometimes I catch myself fast typing H256 instead of HS256 or E512 instead of ES512.
