Setup a Decryption Tool
If your source file is encrypted - setup a Decryption Tool and then provide the reference (result of this function) to the import functions.
h2o.decryptionSetup( keystore, keystore_type = "JCEKS", key_alias = NA_character_, password = NA_character_, decrypt_tool = "", decrypt_impl = "water.parser.GenericDecryptionTool", cipher_spec = NA_character_ )
keystore
: An H2OFrame object referencing a loaded Java Keystore (see example).keystore_type
: (Optional) Specification of Keystore type, defaults to JCEKS.key_alias
: Which key from the keystore to use for decryption.password
: Password to the keystore and the key.decrypt_tool
: (Optional) Name of the decryption tool.decrypt_impl
: (Optional) Java class name implementing the Decryption Tool.cipher_spec
