Is AES encryption symmetric or asymmetric?

¿Cómo funciona el algoritmo de encriptación Rijndael?

AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits. Late last year I change my Firewall S2S and Remote VPN encryption from 3DES/MD5-HMAC to AES-256/SHA-HMAC and saw almost twice speed improvement. My decision to change is after doing a thorough research for which combination is more secure and will be supported in the future. Although 3DES is unbreakable (unlike DES), MD5 and HSA1 is breakable.

Adds support for AES-192-CBC and AES-256-CBC in PEM decoding and DES-CBC, AES-128-CBC, AES-192-CBC and AES-256-CBC in PEM encoding. SHA1 vs SHA2 vs SHA256 – The Secure Hash Algorithm explained. What is the difference between SHA-256, AES-256 and RSA-2048 bit encryptions? expecting to see more algorithms than just DES/3DES/Sha1/MD5. El algoritmo 3DES (Triple Data Encryption Standard), se basa en el algoritmo DES, que aplica una serie de operaciones básicas para convertir Claves.

Una guía para entender Advanced Encryption Standard AES .

The use of AES 256-bit encryption is fairly standard nowadays, and generally speaking in encryption, the longer the key is, the harder it is to crack (and the more secure it is). As we saw, DES relies on the Feistel network in which the data block is divided into two halves before applying the encryption process. AES allows you to choose a 128-bit, 192-bit or 256-bit key, making it exponentially stronger than the 56-bit key of DES. In terms of structure, DES uses the Feistel network which divides the block into two halves before going through the encryption steps. DES Encryption Algorithm: AES Encryption Algorithm: Established as a standard in 1977. Standardized in 2001. Has the key length of 56 bits. It offers key lengths of 128, 192, and 256 bits.
