AES might have been the successor of the DES encryption algorithm, but here\u2019s everything to know about these vastly different methods<\/h2>\n\n\n\n

DES, AES, RSA, ECC \u2014 as someone who\u2019s been covering encryption, I\u2019ve always have complained about the names of these algorithms. First of all, these encryption acronyms sound too dull to communicate the awesome encryption work they do. And the second complaint is that they appear too random for a layman to understand.<\/p>\n\n\n\n

As much as I\u2019d like to write about the former, my fingers are tied to write about the latter. That\u2019s why, in this article, we\u2019ll be focusing upon DES vs AES \u2014 we\u2019ll cover what the DES encryption algorithm is, the AES encryption algorithm, how each is used, and what the differences are between these two extensively used symmetric block ciphers. Let\u2019s get right to it!<\/p>\n\n\n\n

What Is a Symmetric Block Cipher?<\/h2>\n\n\n\n

To know what DES vs AES actually means, you first need to understand what a symmetric block cipher is. Also known as symmetric encryption<\/a> algorithm, a block cipher is a cryptographic algorithm that turns plaintext data into encrypted text (also known as ciphertext). To give you an example, a block cipher might turn “Apple” into something like “2e$5kv7fg*=v#.”<\/p>\n\n\n\n

The transformation from plaintext to ciphertext is carried out using what’s known as a symmetric encryption key, which is a mathematical function. Basically, upon applying this key, the plaintext is turned into blocks of a certain size that are then encrypted. Because it\u2019s a symmetric key, it can also decrypt the encrypted text, which reverts it to its original form.<\/p>\n\n\n\n
