RT

------ Solution --------------------
That is, an md5 encryption

------ Solution --------------------
Region ~~
$ Cryptkey = $ keya. md5 ($ keya. $ keyc );
Connect $ keya with $ keyc first. Then perform md5 encryption, connect the encrypted result with $ keya, and save it as the final encryption result $ cryptkey.
------ Solution --------------------
Give a column
$ Keya = '12'
$ Keyc = '3'
Md5 ($ keya. $ keyc) = md5 ('12'. '3') = 202cb962ac59075b964b07152d234b70
$ Keya. md5 ($ keya. $ keyc) = 12202cb962ac59075b964b07152d234b70
So
$ Cryptkey = $ keya. md5 ($ keya. $ keyc) = 12202cb962ac59075b964b07152d234b70

Hey, haha, it's right on the second floor.
