  • Stavros,
    Hello there,

    You may want to improve your magic base64 encoder / fixer by expecting JWTs!
    While I cannot post/give you mine (of course), you can find more details here: https://jwt.io/introduction/

    I suggest fixes by parsing either the beginning of JWT (ey...) or 3 dots (xxxx.yyyy.zzzz) or underscores and dashes (which can appear after the second dot), all any combination/all of the above!

    I rate the page 10/5
