h2o.decryptionSetup | R Documentation |
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 |
Specification of a cipher (eg.: AES/ECB/PKCS5Padding). |
