Editing Encryption (section)

=== Modern ===
Today, encryption is used in the transfer of communication over the [[Internet]] for security and commerce.<ref name=":1" /> As computing power continues to increase, computer encryption is constantly evolving to prevent [[eavesdropping]] attacks.<ref>{{cite magazine |last1=Newton |first1=Glen E. |title=The Evolution of Encryption |url=https://www.wired.com/insights/2013/05/the-evolution-of-encryption/ |magazine=Wired |others=Unisys |date=7 May 2013 }}</ref> One of the first "modern" cipher suites, [[Data Encryption Standard|DES]], used a 56-bit key with 72,057,594,037,927,936 possibilities; it was cracked in 1999 by [[Electronic Frontier Foundation|EFF's]] brute-force [[EFF DES cracker|DES cracker]], which required 22 hours and 15 minutes to do so. Modern encryption standards often use stronger key sizes, such as [[Advanced Encryption Standard|AES]] (256-bit mode), [[Twofish|TwoFish]], [[ChaCha20-Poly1305]], [[Serpent (cipher)|Serpent]] (configurable up to 512-bit). Cipher suites that use a 128-bit or higher key, like AES, will not be able to be brute-forced because the total amount of keys is 3.4028237e+38 possibilities. The most likely option for cracking ciphers with high key size is to find vulnerabilities in the cipher itself, like inherent biases and [[Backdoor (computing)|backdoors]] or by exploiting physical side effects through [[Side-channel attack]]s. For example, [[RC4]], a stream cipher, was cracked due to inherent biases and vulnerabilities in the cipher.
