- Separate database column for salt 2 answers
Is there a benefit to storing salt appended to hashed password in a single column of a table verses storing salt and hashed password in different columns of the table. The OWASP guide here https://www.owasp.org/index.php/Password_Storage_Cheat_Sheet says 'Store the protected form appended to the salt as follows'
[protected form] = [salt] + protect([protection func], [salt] + [credential]);
