pub fn decrypt_ecdh_es(
token: &str,
local_private_key: &SecretKey,
) -> Result<Vec<u8>, WebexError>Expand description
Decrypt a JWE compact serialization token encrypted with ECDH-ES (or ECDH-ES+A256KW).
The JWE header contains epk (the server’s ephemeral public key).
We use our local private key + the server’s epk to derive the decryption key.
