Decrypt a JWE into BinData
See more JSON Web Encryption (JWE) Examples
Demonstrates Jwe.DecryptBd, which decrypts a recipient of a loaded JWE and writes the plaintext bytes into a BinData.
Background. This is used when the decrypted content is binary. The recipient key must be provided before decrypting.
