Flattened JWE definition.
• ciphertext: string
The "ciphertext" member MUST be present and contain the value BASE64URL(JWE Ciphertext).

The "iv" member MUST be present and contain the value BASE64URL(JWE Initialization Vector) when the JWE Initialization Vector value is non-empty; otherwise, it MUST be absent.
• tag: string
The "tag" member MUST be present and contain the value BASE64URL(JWE Authentication Tag) when the JWE Authentication Tag value is non-empty; otherwise, it MUST be absent.
• Optional aad: string
The "aad" member MUST be present and contain the value BASE64URL(JWE AAD)) when the JWE AAD value is non-empty; otherwise, it MUST be absent. A JWE AAD value can be included to supply a base64url-encoded value to be integrity protected but not encrypted.
• Optional encrypted_key: string
The "encrypted_key" member MUST be present and contain the value BASE64URL(JWE Encrypted Key) when the JWE Encrypted Key value is non-empty; otherwise, it MUST be absent.
• Optional header: JWEHeaderParameters
The "header" member MUST be present and contain the value JWE Per- Recipient Unprotected Header when the JWE Per-Recipient Unprotected Header value is non-empty; otherwise, it MUST be absent. This value is represented as an unencoded JSON object, rather than as a string. These Header Parameter values are not integrity protected.
• Optional protected: string
The "protected" member MUST be present and contain the value BASE64URL(UTF8(JWE Protected Header)) when the JWE Protected Header value is non-empty; otherwise, it MUST be absent. These Header Parameter values are integrity protected.
• Optional unprotected: JWEHeaderParameters
The "unprotected" member MUST be present and contain the value JWE Shared Unprotected Header when the JWE Shared Unprotected Header value is non-empty; otherwise, it MUST be absent. This value is represented as an unencoded JSON object, rather than as a string. These Header Parameter values are not integrity protected.
