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
(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).
Examples
if (FALSE) { # \dontrun{
library(h2o)
h2o.init()
ks_path <- system.file("extdata", "keystore.jks", package = "h2o")
keystore <- h2o.importFile(path = ks_path, parse = FALSE) # don't parse, keep as a binary file
cipher <- "AES/ECB/PKCS5Padding"
pwd <- "Password123"
alias <- "secretKeyAlias"
dt <- h2o.decryptionSetup(keystore, key_alias = alias, password = pwd, cipher_spec = cipher)
data_path <- system.file("extdata", "prostate.csv.aes", package = "h2o")
data <- h2o.importFile(data_path, decrypt_tool = dt)
summary(data)
} # }
