Top Flutter Cryptography, Security and Permissions packages
Last updated: April 2, 2024
Cryptography is the practice of secure communication and is widely used for email, file sharing, messaging and secure communications. Encryption is a key part of cryptography, and is used to protect information from unauthorized access. JWT, RSA, and AES are all examples of cryptographic algorithms that are used to encrypt and decrypt data. JWT is a standard for creating access tokens, RSA is a standard for public-key cryptography, and AES is a standard for symmetric-key cryptography.
