Salesforce OAuth : JWT Bearer Flow by Salesforce notes

WebbAs you can see, with JWT, you get to specify an alg header. There are a lot of options to choose from (including none). There have been ways to exploit JWT libraries by replacing RS256 with HS256 and using the known public key as the HMAC-SHA256 key, thereby allowing arbitrary token forgery. With PASETO, your options are version and a purpose. WebbMost Resource Server support is collected into spring-security-oauth2-resource-server.However, the support for decoding and verifying JWTs is in spring-security-oauth2-jose, meaning that both are necessary in order to have a working resource server that supports JWT-encoded Bearer Tokens.
