The cryptography package provides a comprehensive set of cryptographic algorithms for encryption, digital signatures, key agreement, authentication, and hashing. It supports widely used standards such as AES, Chacha20, and ED25519, ensuring strong security across platforms. Designed for cross-platform use, it works seamlessly on Android, iOS, Web, macOS, Windows, and Linux. Built with Dart, it enables developers to implement secure data handling in applications requiring privacy, integrity, and authentication. The package is maintained by dint.dev and open-source on GitHub.
