How long is the SHA256 hash in MySQL?
As the name “SHA256” suggest, it is 256 bits long. If we are using hexadecimal notation then digit codes represent 4 bits. In order to represent 256, we need 256/4 = 64 bits. We need a data type varchar(64) or char(64).
Creating a table for our example.
mysql> create table SHA256Demo -> ( -> Password varchar(64) -> ); Query OK, 0 rows affected (0.54 sec)
Inserting records into table.
mysql> insert into SHA256Demo values(' 4e2e1a39dba84a0b5a91043bb0e4dbef23970837');
Query OK, 1 row affected (0.18 sec)
Displaying all records.
mysql> select *From SHA256Demo;
The following is the output.
+-------------------------------------------+ | Password | +-------------------------------------------+ | 4e2e1a39dba84a0b5a91043bb0e4dbef23970837 | +-------------------------------------------+ 1 row in set (0.00 sec)
