No way, JOSE!
summary
Starts from concrete mechanics: digital signatures use a private key to sign and a public key to verify, encryption uses public key to encrypt and private key to decrypt, and RSA is demonstrated with small primes 61 and 53 turned into modulus and exponents. Shows that JWS is a three‑part signed compact string and JWE is a five‑part encrypted compact string with an encrypted content key, IV, ciphertext and tag, and exposes a working RSA playground at rsa.tech and JSON key format JWK for real reuse.
