saveFHE: Save and load keys and ciphertexts
In iamtrask/R-Homomorphic-Encryption-Package: Fully Homomorphic Encryption

Description Usage Arguments Details Examples

View source: R/save.R

Use these functions rather than the base R functions for saving and loading of ciphertexts and keys. Note that this is due to a limitation in Rcpp, so the save, save.image and saveRDS base R functions are overriden to warn if they are used incorrectly on ciper text objects.

saveFHE(object, file)

loadFHE(file)

`object`	the ciphertext or keys to be saved
`file`	the filename to save (load) the object to (from)

These functions provide a way to save ciphertexts and keys generated by this package to a file in such a way that they can later be restored to another R session (possibly on a different machine).

At present no compression is performed so for long-term storage or transmission over a network it would be advisable to gzip the files after creation.

p <- pars("FandV")
keys <- keygen(p)
ct1 <- enc(keys$pk, 2)
## Not run: saveFHE(ct1, "~/myCipherText.fhe")

# Start a new session or transfer to another machine
## Not run: ct1 <- loadFHE("~/myCipherText.fhe")
