Struct AdcpeEncryptor 

pub struct AdcpeEncryptor { /* private fields */ }

ADCPE vector encryptor.

Holds a secret orthogonal matrix derived from the encryption key. The matrix is generated via Gram-Schmidt orthogonalization of a seeded pseudo-random matrix.

Implementations

impl AdcpeEncryptor

pub fn new(key: &[u8; 32], config: &AdcpeConfig) -> Result<Self>

Create a new ADCPE encryptor from a 32-byte key.

The key is used to seed a PRNG that generates the random matrix, which is then orthogonalized via Gram-Schmidt.

pub fn encrypt(&mut self, vector: &[f64]) -> Result<Vec<f64>>

Encrypt a single embedding vector.

Returns the transformed vector with the same dimensionality.

pub fn decrypt(&self, encrypted: &[f64]) -> Result<Vec<f64>>

Decrypt a single embedding vector (inverse transformation).

Note: if noise was added during encryption, decryption will not recover the exact original vector.

pub fn encrypt_batch(&mut self, vectors: &[Vec<f64>]) -> Result<Vec<Vec<f64>>>

Encrypt a batch of vectors.

pub fn decrypt_batch(&self, encrypted: &[Vec<f64>]) -> Result<Vec<Vec<f64>>>

Decrypt a batch of vectors.

pub fn dimensions(&self) -> usize

Get the dimensionality.
