Android App Development with Cryptography LIVE Project

In this Android Development with Cryptography, the target is focused on learning how to implement standard Cryptography algorithms in the Android App. This course is very useful to do a live project with primarily getting knowledge about Cipher, Encryption, and Decryption over String and Text.

Topics Discussed

- Android Architecture

- Standard Cipher

One who knows Java can easily get improve their skills like Android Development. This can be considered as the best way to move from Basic Development to Advanced Development.

1. Understanding Cryptography: Before diving into Android app development, it's essential to have a good grasp of cryptography concepts. Some fundamental cryptography terms include:

• Encryption: The process of converting plaintext (human-readable data) into ciphertext (unreadable data) using an algorithm and a key.

• Decryption: The reverse process of converting ciphertext back to plaintext using the same algorithm and a key.

• Symmetric Encryption: Both the sender and receiver use the same key for encryption and decryption.

• Asymmetric Encryption: Different keys are used for encryption and decryption. Public keys are used for encryption, and private keys are used for decryption.

2. Android App Development with Cryptography: To incorporate cryptography into your Android app, you'll need to follow these steps:

a. Choose the Right Cryptography Library: Android provides a robust set of cryptography libraries through the Java Cryptography Architecture (JCA) and Android Keystore. These libraries offer various cryptographic algorithms such as AES, RSA, and ECC, among others. Choose the algorithms that best suit your app's security requirements.

b.  Implement Encryption and Decryption: Once you have your keys securely stored, implement encryption and decryption logic in your app. For example, you can use the AES algorithm for symmetric encryption. Ensure that you follow best practices for key management and handling plaintext data.
