JWT compatibilty (1.5.6 vs 2.6.0)

Token created with JWT 1.5.6 will that be compatible with jwt 2.6.0 and how I can use jwt key finder with 1.5.6 for Json Web keys?

I am using jwt version1.5.6  for encoding with RS256 and keysize 2048. But while decoding I am using jwt version 2.6.0 and encoding and decoding happens on different boxes (while decoding using json web key set to decode) but not sure why I am getting "RSA modulus has a small prime factor".
