encryption - How secure is AES-256? - Cryptography Stack Exchange
Apr 1, 2012 · The cipher AES-256 is used among other places in SSL/TLS across the Internet. It's considered among the top ciphers. In theory it's not crackable since the combinations of keys are …
how does AES encryption's algorithm actually work?
Oct 23, 2015 · AES is described as a sequence of elementary operations called rounds; rounds are (mostly) identical except that they use distinct subkeys (extracted from the main encryption key), and …
encryption - Why use RSA-2048 for plaintext when AES-256 is much …
Jun 8, 2017 · Why do we use RSA encryption for ANY text/communication/data encryption when everybody on internet is writing that AES-256 is much stronger than RSA-2048? If this is true, why …
RSA maximum bytes to encrypt, comparison to AES in terms of security?
Mar 30, 2013 · Performance of encryption and decryption for the actual conversation data is very good. In terms of level of security, it doesn't really make much sense to compare RSA and AES.
Is AES-256 a post-quantum secure cipher or not?
AES-256 is generally considered which is why no need for a post quantum counterpart. This is why I prefer "Quantum-Safe Cryptography" to denote all algorithms that are safe against quantum …
