Function jsonwebtoken::dangerous_insecure_decode

pub fn dangerous_insecure_decode<T: DeserializeOwned>(
    token: &str
) -> Result<TokenData<T>>

Decode a JWT without any signature verification/validations.

NOTE: Do not use this unless you know what you are doing! If the token’s signature is invalid, it will not return an error.
