Secure Notes Elite: Encrypt Notes & Files AES 256 for Android
AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits. By contrast, Rijndael per se is specified with block and key sizes that may be any multiple of 32 bits, with a minimum of 128 and a maximum of 256 bits. AES operates on a 4 × 4 column-major order array of bytes, termed the state. How to do AES 256 Encryption & Decryption in Android Jun 27, 2020 Full-Disk Encryption | Android Open Source Project
What is AES-256 Encryption? - Cyclonis
I use Delphi 10.2 Version 25.0.29899.2631 (update 3) PE with FMX for developping IOS and Android apps. To make my app (FMX) more secure I like to use AES-128 (or AES-256) to encrypt/decrypt some strings. (with the assumption AES-128/256 is nowadays the way to go for encryption).
AES Crypt is an advanced file encryption utility that integrates with the Windows shell or runs from the Linux command prompt to provide a simple, yet powerful, tool for encrypting files using the Advanced Encryption Standard (AES). A Java library is also available for developers using Java to read and write AES formatted files.
AES was designed to replace DES, and is generally thought to be better in all respects. AES has three flavors, dubbed AES-128, AES-192 and AES-256, which differ by the key length (of 128, 192 and 256 bits, respectively). 128 bits are more than enough for security, and longer keys imply a slight computational overhead, so a 128-bit key is preferred.
