Description:
AES 是一种使用安全码进行信息加密的标准。
它支持 128 位、192 位和 256 位的密匙。
加密算法的实现在 ElAES.pas 单元中。
本人将其加密方法封装在 AES.pas 单元中，
只需要调用两个标准函数就可以完成字符串的加密和解密。
(* 密匙长度 *)
128 位支持长度为 16 个字符
192 位支持长度为 24 个字符
256 位支持长度为 32 个字符
所有加密和解密操作在默认情况下为 128 位密匙。-A popular method of product validation is using keys similar to VJJJBX-H2BBCC-68CF7F-2BXD4R-3XP7FB-JDVQBC. These compact keys can be derived using Symmetric Key Cryptosystems such as the Advanced Encryption Standard (AES).
Other Public Key Cryptosystems are available such as RSA. However, these systems generally produce larger keys (which the user will eventually have to enter into the program to unlock functionality). Smaller producing Cryptosystems exist, but it is the author s opinion that they are highly encumbered with patents. Quartz is one such example. It is a Public Key Encryption System that produces a smaller cipher text based on Hidden Field Equations (HFEs). The Quartz website is littered with phrases such as "must license" and "pay royalties".
The reader is also encouraged to investigate Signature Schemes (with Recovery) as an alternative method to producing Product Keys. An example is PSS-R, a Message Recovery Signature Scheme based on RSA. PSS-R is not suitable fo Platform: |
