I rewrote it quickly to C [1] (and changed the embedded binary to be aarch64).

Unfortunately it fails on calling bind() on my device, so probalby Android doesn't ship with that kenrel module by default :(. So no freedom for my $40 phone.

Putting it out here, maybe somebody else will have better luck.

Update: Checking the kernel config indeed confirms this.

   adb shell zcat /proc/config.gz | grep CONFIG_CRYPTO_USER_API
   # CONFIG_CRYPTO_USER_API_HASH is not set
   # CONFIG_CRYPTO_USER_API_SKCIPHER is not set
   # CONFIG_CRYPTO_USER_API_RNG is not set
   # CONFIG_CRYPTO_USER_API_AEAD is not set
