Section titled “miniproto.crypto.native.aes_256_ige_encrypt”
aes_256_ige_encrypt(plaintext: bytes, key: bytes, iv: bytes) -> bytes

Encrypt block-aligned bytes with AES-256-IGE.

Parameters:

  • plaintext (bytes) – Bytes whose length is a multiple of 16; no padding is added.
  • key (bytes) – Exactly 32 bytes of AES-256 key material.
  • iv (bytes) – Exactly 32 bytes: previous ciphertext followed by previous plaintext.

Returns:

  • bytes – Ciphertext equal in length to plaintext.

Raises:

  • ValueError – If key/IV lengths or block alignment are invalid.

This selects the loaded backend. IGE supplies no standalone authentication; use it only in the MTProto construction that defines its integrity checks.
