/**
 * EncryptedDataCMS
 *
 * EncryptedData is defined differently in different RFCs.
 * RFC5652 (CMS) defines it one way:
 *
 * https://datatracker.ietf.org/doc/html/rfc5652#page-30
 *
 * RFC5208 (PKCS8) defines it another way:
 *
 * https://datatracker.ietf.org/doc/html/rfc5208#page-4
 *
 * This class implements the RFC5652 EncryptedData definition.
 *
 * The only difference between RFC5652's EncryptedData and RFC5652's EnvelopedData
 * is that EnvelopedData has originatorInfo (optional) and recipientInfos (required)
