Description

If your source file is encrypted - setup a Decryption Tool and then provide the reference (result of this function) to the import functions.

Usage

h2o.decryptionSetup(keystore, keystore_type = "JCEKS",
  key_alias = NA_character_, password = NA_character_, decrypt_tool = "",
  decrypt_impl = "water.parser.GenericDecryptionTool",
  cipher_spec = NA_character_)

Arguments

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
