Generate 256 Bit Key Jwt
Direct JSON Web Encryption (JWE) with a shared symmetric key. The simplest kind of JSON Web Encryption (JWE) is direct encryption with a symmetric AES key, hence the algorithm designation dir. Sender and recipient must share the same secret key, established by some out-of-band mechanism, unless you have a use case where the plain text is. How to generate a JSON Web Key (JWK) JSON Web Keys (JWK) can be easily generated with the help of the Nimbus JOSE+JWT library. RSA keys; Elliptic curve keys; Edwards curve keys; Secret keys; Cryptographic keys can also be generated in some other environment and then converted into JWK format. Must be one of P-256, P-384, P-521 -i Key ID (optional) -p Display public key separately -s Key Size in bits, required for RSA and OCT key types. Must be an integer divisible by 8 -S Wrap the generated key in a KeySet -t Key Type, one of: RSA, oct, EC -u Usage, one of: enc, sig (optional) Example. To generate a 2048-bit.
Signing and encryption order
JSON Web Tokens (JWT) can be signed then encrypted to provide confidentialityof the claims.
While it's technically possible to perform the operations in any order tocreate a nested JWT, senders should first sign the JWT, then encrypt theresulting message.
Why is sign-then-encrypt the preferred order?
Prevents attacks in which the signature is stripped, leaving just anencrypted message. Walking dead final season pc.
Provides privacy for the signer.
Signatures over encrypted text are not considered valid in somejurisdictions.
Certain papers advocate applying a second signature after theencryption. Thisisn't required with standard JWE algorithms due to their use of authenticatedencryption.
Producing a nested JWT
Let's create a JWT which is signed (JWS) with the sender's private RSA key andthen encrypted (JWE) with the recipient's public RSA key.
For that sender and recipient each must first generate their own RSA key pairs,and distribute the public key of each generated pair to the other party.
Generate sender RSA key pair, make public key available to recipient:
Generate recipient RSA key pair, make public key available to sender:

The recipient will first need to decrypt the JWE object, then extract thesigned JWT from its payload and verify the signature.
