Overview
The encrypt package provides high-level, easy-to-use APIs for two-way cryptography in Flutter applications, built on top of PointyCastle. It simplifies encryption and decryption processes with support for various algorithms like AES, RSA, and DES. Designed for developers needing secure data handling, it enables safe storage and transmission of sensitive information across multiple platforms. The package abstracts low-level cryptographic complexities, making secure coding accessible even to those without deep cryptography expertise.
