不错的希尔代码，希尔是一种经典的加密算法，加密可以通过一线形变换，脱密再做依次逆变换。密钥就是变换矩阵本身。-good code Hill, Hill is a classic encryption algorithms, encryption can transform line shape, followed again from close inverse transform. Key is the transformation matrix itself.

RSA算法伪代码，可能还不够成型，仅供大家学习参考用-RSA algorithm pseudo-code, might not be enough shape for them to learn from reference
