PHP implementation and C # consistent DES encryption and decryption instance

This article mainly introduces the implementation of PHP and C # consistent DES encryption and decryption instance, has a certain reference value, now share to everyone, the need for friends can refer to

PHP implementation and C # consistent DES encryption decryption, can be searched from the internet to a large heap, but the test found no use. The following are the correct codes that I found after a hard struggle. I hope you can use it when the system is integrated.

Note: The length of the key is within 8 bits.
