Cipher
Introduction
This sample shows how to use cipher algorithms, including Rivest-Shamir-Adleman (RSA) and Advanced Encryption Standard (AES). The display effect is as follows:
Concepts
RSA: A public-key cryptosystem that works on two different keys: a public encryption key and a private decryption key.
AES: A block encryption standard established by the U.S. National Institute of Standards and technology (NIST). It is also called Rijndael.
Required Permissions
N/A.
Usage
-
On the home screen, touch the Encrypt button. On the Encrypt screen, select an encryption algorithm from the Encryption Algorithm drop-down list box, enter the content to be encrypted in the text box, and touch the Encrypt button.
The encrypted content is displayed in the text box below.
-
Touch the Reset button to clear the content in the text box.
-
Touch the Decrypt button on the home screen. On the Decrypt screen, select a decryption algorithm from the Decryption Algorithm drop-down list box, enter the content to be decrypted in the text box, and touch the Decrypt button.
The decrypted content is displayed in the text box below.
-
Touch the Reset button to clear the content in the text box.
Constraints
