Can we convert MD5 to SHA256 in a MySQL table with user password column?
Use SHA2() to convert the MD5 password to SHA256. It calculates the SHA-2 family of hash functions i.e. SHA-224, SHA-256, SHA-384, and SHA-512).
Let us first create a table −
mysql> create table DemoTable818(UserPassword text); Query OK, 0 rows affected (0.51 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable818 values(MD5('John_123')); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable818 values(MD5('999Carol@22')); Query OK, 1 row affected (0.14 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable818;
This will produce the following output −
+----------------------------------+ | UserPassword | +----------------------------------+ | 47c7d0987db4e59e2264ce9fefce4977 | | 950aa70edd5b686a807b3bfffdf2248c | +----------------------------------+ 2 rows in set (0.00 sec)
Following is the query to convert MD5 to SHA256 −
mysql> update DemoTable818 set UserPassword=SHA2(UserPassword,256); Query OK, 2 rows affected (0.19 sec) Rows matched: 2 Changed: 2 Warnings: 0
Let us check the table records once again −
mysql> select *from DemoTable818;
This will produce the following output −
+------------------------------------------------------------------+ | UserPassword | +------------------------------------------------------------------+ | 8b68c46294a9ccb2449324c24fe774f95b7c14e4b56fc51c7f8e6c5b01c7020f | | 9cc80741546051ae3de7d31246327968c98af3c65125376acb7b49a0760d42a3 | +------------------------------------------------------------------+ 2 rows in set (0.00 sec)
