Description:
polarsencryption 0.1.0
Polars Encryption
This is a plugin to extend Polars with encryption algorithm AES-GSM-SIV written in Rust for a blazing fast (c) performance.
Sources
This plugin is built using a guide by Marco Gorelli.
The encryption algorithm crate is this. The specific implementation is a 256bit version of it.
Usage
There are two methods: encrypt and decrypt. Both require key and nonce, as per algorithm specification.
import polars as pl
from polars_encryption import encrypt, decrypt
# Define the DataFrame
df = pl.DataFrame({
"plaintext": ["Hello, world!", "Polars is fast!", "Encrypt me!"]
})
# Define the encryption key and nonce
key = b"an example very very secret key."
nonce = b"unique nonce" # 12 bytes (96 bits)
# Encrypt the plaintext column
df_encrypted = df.with_columns(
encrypt(pl.col("plaintext"), key=key, nonce=nonce).alias("ciphertext")).with_columns(decrypt(pl.col("ciphertext"), key=key, nonce=nonce).alias("decrypted"))
print((df["plaintext"] == df_encrypted["decrypted"]).all())
print(df_encrypted)
