JSON Web Encryption (JWE) component o .NET 4.8 using RSA or EC keys.

Obtains public RSA and/or EC keys from a JWKS REST Service o Caches the public keys o Refreshes the public keys each hour.

Uses the public key to encrypt a PII string and creates a JWE encode string o For RSA key, uses RSA_OAEP_256 and A256GCM o For EC key, uses ECDH_ES_A256KW and A256GCM

Uses the private key to decrypt a JWE encode string o The public Key Id must be the same as the private Key Id.

C# ASP.NET MVC Sample Code:

appsettings.json

{ "EncryptionOptions": { "JwksUrl": "http://localhost:31102/api/jwks/v1/lab01/getjsonwebkeys", "CacheDurationSeconds": 3600 // 1 hour } }
