Rijndael
Rijndael,在高級加密標準（AES）中使用的基本密碼算法。
概述
（美國）國家標準技術研究所（NIST）選擇Rijndael作爲美國政府加密標準（AES）的加密算法，AES取代早期的數據加密標準（DES）。Rijndael由比利時計算機科學家Vincent Rijmen和Joan
Daemen開發，它可以使用128位，192位或者256位的密鑰長度，使得它比56位的DES更健壯可靠。Rijndael也有一個非常小的版本（52位），合適用在蜂窩電話、個人數字處理器（PDA）和其他的小設備上。
近似讀音：Rijn [rain] dael [del] (萊恩戴爾)
Rijn 來源 Rhine [萊茵河]的荷蘭語(Dutch)發音。
dael 是常用的人名 這詞是兩個科學家的名字各出一段拼成的。
