Once active, you can decode JWTs from the Linux command line with relative ease: Use the JWT Decoder tool to decode an encoded JWT Token and see the contents in clear text. After a couple of slight modifications I was super stoked with the following jq incantation (huge thanks Lucas!):
Using bearer tokens for authentication relies on the security provided by an encrypted protocol, such as HTTPS if a bearer token is intercepted, it can be used by a bad. Access tokens, ID tokens, and self-signed JWTs are all bearer tokens.

While looking into command line JWT decoders, I came across the following gist describing how to do this with jq. Bearer tokens are a general class of token that grants access to the party in possession of the token. There are plenty of online tools available to decode JWTs, but being a command line warrior I wanted something I could use from a bash prompt. The most common form of bearer token is the JWT (JSON Web Token), which is a string with three hexadecimal components separated by periods (e.g., ). At the core of OAUTH2 is the concept of a bearer token. This tool is designed as a JWT debugger to demonstrate how JWT works.Over the past few months I’ve been spending some of my spare time trying to understand OAUTH2 and OIDC. However, for security purposes, it is advised to protect your signing keys and public/private key pairs from any 3rd party tool including 10015.io (even if it is a client-side tool) if this information is crucial for you application. This data is not transferred to any server. Information regarding any JWT that is generated or decoded in this tool including signing keys, public and private key pairs are used only in your browser. If all required fields are filled and there is no problem about parsing the input, you will get your result from the output field. When all configuration is completed, click the button "Encode" or "Decode" according to your needs.Make your configuration for encoding/decoding and fill signing keys if needed.If you want to decode a JWT, fill input field with the JWT that you want to decode. JWT.IO allows you to decode, verify and generate JWT. If you want to generate a JWT, fill input field with the payload. JSON Web Tokens are an open, industry standard RFC 7519 method for representing claims securely between two parties.You can encode, decode, or debug a JWT by using these steps.

Otherwise, your signing key may be cracked with brute force. If you are using HSxxx (symmetric) algorithms, for security reasons, it is advised to have 256 bit (32 characters), 384 bit (48 characters), 512 bit (64 characters) and longer signing keys for HS256, HS384 & HS512 respectively. Even if the signature is invalid, you will still see the payload and header of the JSON web token. Meta data of the token is stored in the header section like what is the algorithm etc.įor JWT decoding, you can either verify the signing key or not. Even if they are not mandatory, it is advised to use them for defining the data and data validity better. There are some predefined claims such as "iss" (issuer), "exp" (expiration time), "sub" (subject), "aud" (audience) that is stored in the payload of a JWT. When you send data from server to client and get it back, you verify your data with this signature. Signature is very important for securely transferring this data. Header and payload of the JWT can be seen by everyone after decoding. Therefore, all JWT have a structure of "". There are 3 parts of a JWT which are separated with dots.
If there is one key that is used both for encoding and decoding JWT, it is called symmetric algorithm, if there is a public/private key pair, then it is called asymmetric algorithm. Private key is using in encoding while public key is used for decoding JWT. HSxxx algorithms works with a single signing key as a string while RSxxx and ESxxx algorithms works with a public & private key pair. 37.3k 5 94 142 Add a comment 35 You can split with space using TokenArray jwttoken. If you are concerned about privacy, youll be happy to know the token. There are 9 algorithms available which are HS256, HS384, HS512, RS256, RS384, RS512, ES256, ES384 and ES512. Tooltips help explain the meaning of common claims. You can use this tool as an online JWT debugger, so you can sign a JWT with a signing key or private key, verify a JWT with a signing key or public key, or just decode a JWT without verifying the signature. JWT is a standard for transferring JSON data securely by signing it with a key.
