Potentially related: #70924

Code

I don't think this is related to a piece of code. This ICE occurred after writing some new code, but the panic mentions unchanged existing code.

Here's the code it panicked on then:

pub fn encrypt(key: &[u8], decrypted: &[u8]) -> Result<Encrypted> {
    let key = Key::from_slice(key);
    let cipher = XChaCha20Poly1305::new(key);

    let mut nonce_bytes = [0u8; 24];
    rand::thread_rng().fill_bytes(&mut nonce_bytes);
    let nonce = XNonce::from(nonce_bytes);

    let encrypted = cipher.encrypt(&nonce, decrypted).map_err(|_| HttpError::ChaCha20Poly1305)?;
    Ok(Encrypted {
        ciphertext: encrypted,
        nonce: nonce_bytes.to_vec(),
    })
}

and:

pub fn decrypt(key: &[u8], nonce: &[u8], encrypted: &[u8]) -> Result<Vec<u8>> {
    let key = Key::from_slice(key);
    let cipher = XChaCha20Poly1305::new(key);
    let nonce = XNonce::from_slice(nonce);
    let decrypted = cipher.decrypt(nonce, encrypted).map_err(|_| HttpError::ChaCha20Poly1305)?;
    Ok(decrypted)
}

Ah, didn't notice that one. This one can be closed then I think.
