Create a new DataKeyContext object

Parameters:

  • mongocrypt (Mongo::Crypt::Handle)

    a Handle that wraps a mongocrypt_t object used to create a new mongocrypt_ctx_t

  • io (Mongo::Crypt::EncryptionIO)

    An object that performs all driver I/O on behalf of libmongocrypt

  • master_key_document (Mongo::Crypt::KMS::MasterKeyDocument)

    The master key document that contains master encryption key parameters.

  • key_alt_names (Array<String> | nil)

    An optional array of strings specifying alternate names for the new data key.

  • :key_material (String | nil)

    Optional 96 bytes to use as custom key material for the data key being created. If :key_material option is given, the custom key material is used for encrypting and decrypting data.
