Hi everyone, I need to crypt a string with a tool (not the app) and then be able to decode it back from the app.
example tool: https://encode-decode.com/aes256-encrypt-online/
1. Crypt a text with the above tool
2. Copy the output string (e.g. Kj7ytYpr5Z/g93JaBEUo9Q==)
3. Use that string in the...
Hi all,
I use the nice B4XAES library in B4J and B4A.
In the post https://www.b4x.com/android/forum/threads/b4x-b4xaes-v2-0-encryption-decryption-b4xlib-b4a-b4i-b4j.141536/ it says that the lib can also be used in b4i.
Reason to use this is of the good Encryption and has to be compatible with...
I'm new to encryption, btw, and I want to be able to compare encrypted mysql data on the fly while executing a select query like
SELECT * from myTable WHERE
encrytedField=selectedEncryptedValue
or
SELECT * from myTable WHERE
aes_decrypt(encrytedField, '123')=selectedValue
Therefore I need...
This is about how to exchange AES256 encrypted messages incl. generated IV (initialization vector) between a ESP32 and B4x.
Notes:
- the ESP uses AES/CBC/NoPadding. The data must be padded (must have a length which is a multiple of 16). I've used a length of 256 to to get there (instead of...
Finally I got it working. Maybe the Inline C code is not that elegant :) I was too lazy to add a Salt (which I will update later). Hardest part (for me as I don't like C since the 90ies) was to exchange the data between B4R Main and the Inline C. However: I got it.
Note: As PKCSNoPadding ist...
I've found examples in C but I'm not experienced with inline C. Could someone adapt these examples to usable inline code?

This class can be used decrypt data created with LockBox3 and encrypt data that will be properly handled by LockBox3. LockBox3 is an encryption/decryption library for Delphi.
There are actually three classes, LB3AES, LB3AESECB and LB3AESCBC. The only class that is used to instantiate an object...
