    # Not applicable to this crate. We only ever ENCRYPT with IG's public
    # key in `session::encryption::encrypt_password` (RsaPublicKey::encrypt),
    # never decrypt. The Marvin attack requires a victim that decrypts
    # ciphertexts and exposes timing information; we hold no private key
    # and run no decryption code. See SECURITY.md for the full rationale.
    #
    # This ignore should be removed once `rsa` ships a fix
    # (https://github.com/RustCrypto/RSA/issues/19).
