**TgCrypto** is a Telegram Crypto Library written in C89 as a Python extension. It is designed to be portable, fast, easy
|

|

cryptographic algorithms Telegram requires, namely:
|
||||
|
||||
- **`AES256-IGE`** - used in [MTProto v2.0](https://core.telegram.org/mtproto).
|
||||
- **`AES256-CTR`** - used for [CDN encrypted files](https://core.telegram.org/cdn).
|
||||
- **`AES256-CBC`** - used for [encrypted passport credentials](https://core.telegram.org/passport).
|
||||
|
||||
Python [wheels are available](https://pypi.org/project/TgCrypto/#files) for hassle-free installations; they are
|
||||
automatically built and tested using Travis CI for Linux (i686, x86_64, AArch64), Windows (32-bit, 64-bit) and macOS
|
||||
(x86_64).
|
||||
|
||||
Even though TgCrypto is primarily intended for use with Pyrogram, you are free and welcome to use it for any other
|
||||
Python project too, as it's shipped as standalone package.
