JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA or ECDSA.

Ways to attack

I builded my own JWT in my custom format using aes256 with two times crypted. So, for enybody to hack that and find secret key will need 2560 years to decrypt. Thats why i use my own strategy to crypt tokens.
