No way, JOSE!
summary
Explains concrete cryptography steps: hashing and HMAC (SHA-256 and HMAC-SHA256), signature vs keyed MAC, RSA key generation and why 2048+ bits matter, and how to process a three-part JWS and a five-part JWE (RSA-OAEP to unwrap a content key, then AES-GCM to decrypt). Shows examples, links slides at jose.samvega.tech and an interactive rsa.samvega.tech demo that works in Chromium/Firefox but not Safari, and names algorithms like a256GCM and RSA-OAEP so implementers know what libraries and sequence to use.
