25 нояб. 2013 г. · To create a secure key, use a KeyGenerator that is based on a properly seeded cryptographic random number generator.

14 июл. 2017 г. · You should give PBEKeySpec what it needs to generate enough bits for an AES key. You need the same salt on both sides, so you could do:

20 окт. 2019 г. · Let's do it step by step to keep things simple. You need two methods to achieve your goal. I'll start with encryption method.

28 окт. 2019 г. · The simplest and most common way to achieve both uniqueness and unpredictability is to use a secure Random Number (aka Bit) Generator such as Java's ...

19 сент. 2011 г. · I have to generate keys just from a password (with no salt and no iterations), and I need them to work for AES-128, AES-192 and AES-256.

18 сент. 2020 г. · I want to create an AES key that will encrypt my database (SQLCipher). Then this key will be encrypted by the generated public key and kept in ...

15 сент. 2022 г. · An AES key is simply a random byte sequence that is 16, 24 or 32 bytes long. keyGenerator.generateKey().getEncoded() returns this byte sequence.

22 апр. 2018 г. · TL;DR: use a better password and bring back the iterations and use a KBKDF2 to derive the AES and HMAC keys.

6 нояб. 2015 г. · I'm creating a chat application where the connections are done via SSL/TLS, and the messages are encrypted using AES-CBC-256 and the AES keys are encrypted ...

29 дек. 2019 г. · I need to figure out how to generate a random 256 AES CBC key with PKCS5 padding in Dart for my Flutter project.
