8 Best Encryption Packages for Flutter in 2023

Encryption is the process of transforming readable data into an unreadable format to protect its privacy. This can be done in a lot of different ways, but one of the most common methods is to use a cryptographic algorithm. This will scramble the data so that it can’t be read without the correct key.

There are a lot of different encryption packages available for Flutter, and it can be tough to know which one is the best for your needs. To help you out, we’ve compiled a list of the five best encryption packages available. Whether you’re looking for something simple or something more robust, there’s an encryption package on this list that will suit your needs. So read on to find out more about the best encryption packages for Flutter!

The Best Encryption Packages for Flutter


steel_crypt is a comprehensive library of high-level cryptographic APIs. Whether you need to hash data, encrypt sensitive information, or generate keys and IVs, this library has everything you need. It also comes with a handy CLI, making it easy to get started with cryptography operations.


Cryptography is essential for protecting your data online. The cryptographic algorithms can help you encrypt your communications, signatures, and more. With Web Crypto support, you can use cryptography in your web applications as well.
