IDEA加密算法属于数据块加密算法(Block Cipher)类。IDEA使用长度为128bit的密钥，数据块大小为64bit。-IDEA encryption algorithm is data block encryption algorithm (Cipher Block) category. IDEA use of the length of the 128 bit key, the data block size for 64bit.

密码学文献有一个奇妙的发展历程，当然，密而不宣总是扮演主要角色。第一次世界大战前，重要的密码学进展很少出现在公开文献中，但该领域却和其它专业学科一样向前发展。-cryptography literature has a wonderful history, of course, close does not declare always played the leading role. Before the First World War, it was important to cryptography little progress emerged in the open literature. However, the area has other professional disciplines and the development of the same.
