This script creates two stored procedures in the master database. The procedures are named sp_hexadecimal and sp_help_revlogin
Run the following statement:
EXEC sp_help_revlogin
The output script that the sp_help_revlogin stored procedure generates is the login script. This login script creates the logins that have the original Security Identifier (SID) and the original password.
