Run the following command:
openssl req -new -x509 -days 365 -nodes -out /etc/apache2/ssl/apache.pem -keyout /etc/apache2/ssl/apache.key
First archive the directory using 7zip.
7z a filename.7z targetdirectory
Next, encrypt the file using OpenSSL. Executing the command will ask the user for a password
openssl aes-256-cbc -in filename.7z -out file.enc
You can decrypt the file using the following command. Executing the command will ask the user for a password.
openssl aes-256-cbc -d -in file.enc -out filename.7z

It’s suggested you use SQL Profiler trace data ove layed against system information found in the performance monitor. However, to get a quick look at what queries may be slowing down performance , run the following -
, sum(s.execution_count) sum_execution_count
, sum(s.total_elapsed_time) sum_total_elapsed_time
, sum(s.total_worker_time) sum_total_worker_time
, sum(s.total_logical_reads) sum_total_logical_reads
, sum(s.total_logical_writes) sum_total_logical_writes
from sys.dm_exec_query_stats s
group by s.plan_handle
) as ss
cross apply sys.dm_exec_sql_text(ss.plan_handle) t
order by sum_total_logical_reads DESC

Use the update-rc.d command.
First remove the link fron the /etc/init.d directory to the rc.d directories
sudo update-rc.d -f my_old_script remove
Then change the boot order. The following updates the scripts boot order to 98.
sudo update-rc.d my_script defaults 98
This command can also be used to remove or add a service during boot.
First convert the .pfx file to .pem format
openssl pkcs12 -in ClientCert1.pfx -out privpub.pem
Then extract the public key from the .pem format:
openssl x509 -inform pem -in privpub.pem -pubkey -out pub.pem -outform pem
