Don't panic if your backend-server uses https:// (RSA) (it's quite safe) 6. Not using https:// is VERY unsafe 5. Happy en-/decryption!

Interesting reading about encryption algorithms here Here's another page (Parts from the page below) There’s a host of different encryption algorithms available today. Here are five of the more common ones. AES. The Advanced Encryption Standard (AES) is the trusted standard algorithm used by th

Whoever told you that? It's nonsense. AES is a standard.

This example is based on agrahams encryption library: Encryption Lib 1. Generate a 32 byte pw (just call the sub) and store it 2. Encrypt the data by calling AES_Encrypt. Return is a byte array or a base64 encoded string 3. Salt is a random value which is added at the beginning of the encrypted str

“AES” is a class that is defined based on the windows’ RijndaelManaged class (https://docs.microsoft.com/en-us/dotnet/api/system.security.cryptography.rijndaelmanaged?view=netframework-4.8) which is basically the code as above. Not 100% sure on how to do the same thing in B4X (I thought I was doing

AES is Advanced Encryption Standard. Used tons of times from tons of devices, from microcontroller with AES128 to more robust solutions with 256. Personally i would never try to create a cipher alghoritm myself because it will be too weak. This is the example code that works with the PHP snippet ab

See my examples. AES is perfect for that.

Try B4XEncryption library.
