Length of signature

[filipgrzelak]

i have got 2048 bit key and i want to sign a data.
After i sign a data with var sig = new KJUR.crypto.Signature({"alg": "SHA256withRSA"})
sig.init(keyObj)
sig.updateString(dataToSign)
var result = sig.sign()
return btoa(result)

after that when i send a request i have got error that my signature is 512 length but expected was 256
why i have this error?
