Tiny AES C
tiny-AES-c is a lightweight C language cryptography library that provides a symmetric cipher implementation of the Advanced Encryption Standard. It functions as a portable set of functions for encrypting and decrypting data using a shared secret key.
The library is designed for embedded system security, enabling cryptographic operations on hardware with limited memory and processing power. It provides these capabilities without relying on large external dependencies.
The implementation utilizes a standard C library approach, employing table-based substitution and in-place buffer mutation to perform data transformations.
