23. DES_quad_cksum:is a Kerberos v4 function. It returns a4 byte checksum from the input bytes. The algorithm can be iterated over the input, depending onI<out_count>, 1, 2, 3 or 4 times. If I is non-NULL, the 8 bytes generated by each pass arewritten into I. 24. DES_fcrypt...
Finally, it gives a brief description of security risks that existed in DES encryption algorithm and proposed the application errors of DES encryption algorithm. Key words: Data security and computer security; DES encryption algorithm; File transfer 0 引言 在 信息化的时代 里,数据是承 载信息的基...
