-# Test vectors for TFHE
-These test vectors are generated using [TFHE-rs](https://github.com/zama-ai/tfhe-rs), with the git tag `tfhe-test-vectors-0.2.0`.
-
-They are TFHE-rs objects serialized in the [cbor format](https://cbor.io/). These can be deserialized using any cbor library for any programming languages. For example, using the [cbor2](https://pypi.org/project/cbor2/) program, the command to run is: `cbor2 --pretty toy_params/lwe_a.cbor`.
-
-There are 2 folders with test vectors for different parameter sets:
-- `valid_params_128`: valid classical PBS parameters using a Gaussian noise distribution, providing 128-bits of security in the IND-CPA model (i.e., the probability of failure is smaller than 2^{-64}).
-- `toy_params`: insecure parameters that yield smaller values to simplify the bit comparison of the results.
-
-The values are generated to compute a keyswitch (KS) followed by a bootstrap (PBS). The cleartext inputs are 2 values, A and B defined below.
-
-All the random values are generated from a fixed seed, that can be found in the `RAND_SEED` constant below. The PRNG used is the one based on the AES block cipher in counter mode, from tfhe `tfhe-csprng` crate.
-
-The bootstrap is applied twice, with 2 different lut, the identity lut and a specific one computing the double of the input value (i.e., f(x) = 2*x).
-
-## Vectors
-The following values are generated:

-
-Ciphertexts with the `_karatsuba` suffix are generated using the Karatsuba polynomial multiplication algorithm in the blind rotation, while default ciphertexts are generated using an FFT multiplication.
-This makes it easier to reproduce bit exact results.
-
-### Encodings
-#### Non native encoding
-Warning: TFHE-rs uses a specific encoding for non native (ie: u32, u64) power of two ciphertext modulus. This encoding puts the encoded value in the high bits of the native integer.
-For example, the value 37 with a modulus of 64 will be encoded as `0b1001010000000000000000000000000000000000000000000000000000000000`. This matters for the post modswitch lwe ciphertext.
-
-#### Ciphertext modulus
-The ciphertext modulus encoding use a specific value for the native modulus: 0. For example, if values are stored on u64 integers, 0 means a ciphertext modulus of 2^64.
