A Problem with Cowboy Coding

As we implement more automation and complexity in our systems, we increase the ability of every worker to accomplish more during their day. In many cases, this is a good thing, as many of us have no shortage of tasks to complete. Being able to do more is good. Some technology workers, and likely some managers, view these changes as opportunities to use less people to do the same work. That can be worrisome for many people, especially those concerned with job security. That's a difficult situation to find one's self in.

I'm not sure if this worker was concerned about losing employment or just wanted to get more work, but a contractor put logic bombs in his project that would cause issues at various times. He would then be called to fix issues, getting paid for his efforts. Recently he was sentenced to prison time for his actions.

Most workers make an effort to do good work and provide value for their time and knowledge. They may still make mistakes or cause problems, but it's often unintentional, not malicious. We also don't look to create future problems for others, though certainly we may accrue technical debt over time as we make trade-offs in our work.

Whether intentional or accidental, we want to limit mistakes and issues in our code. This is one reason that modern development in a DevOps environment isn't a wild west, cowboy style of work. We use code reviews and continuous improvement to help other developers learn to write better code. We use automated processes with instrumentation and logging to ensure we know what code is deployed when and by whom.

We may move faster with DevOps, but it's often safer, more secure, and more accountable than previous methods of building software. It doesn't prevent mistakes, but every part of the process should be more transparent and auditable, which is good for everyone involved.

Free eBook: SQL Server Execution Plans, Third Edition

Press Release from Redgate

If a query is performing poorly, and you can't understand why, then that query's execution plan will tell you not only what data set is coming back, but also what SQL Server did, and in what order, to get that data. It will reveal how the data was retrieved, and from which tables and indexes, what types of joins were used, at what point filtering, sorting and aggregation occurred, and a whole lot more. These details will often highlight the likely source of any problem.

  Yesterday's Question of the Day (by Steve Jones - SSC Editor)

Changing Algorithms

I create a symmetric key in a SQL Server 2016 database. I use this code:

CREATE SYMMETRIC KEY SalaryKey
WITH ALGORITHM = AES_256
, IDENTITY_VALUE = 'Salary Protection'
, KEY_SOURCE = 'Protect this from hackers'
ENCRYPTION BY PASSWORD = 'SomeReallyStr0ngP@ssword';
GO

I then use this to encrypt some data in a table:

OPEN SYMMETRIC KEY SalaryKey DECRYPTION BY PASSWORD  = 'SomeReallyStr0ngP@ssword'

UPDATE dbo.Employees
 SET EncryptedSalary = ENCRYPTBYKEY(KEY_GUID('SalaryKey'), CAST(Salary AS VARCHAR(50)))
GO

I now transfer this data to a SQL Server 2017 database, into the same structure table. Now I run this:

CREATE SYMMETRIC KEY SalaryKey
WITH ALGORITHM = AES_256
, IDENTITY_VALUE = 'Salary Protection'
, KEY_SOURCE = 'Protect this from hackers'
ENCRYPTION BY PASSWORD = 'SomeReallyStr0ngP@ssword';
GO
OPEN SYMMETRIC KEY SalaryKey DECRYPTION BY PASSWORD  = 'SomeReallyStr0ngP@ssword'
SELECT top 10
 e.EmpID
, e.EmpSSN
, e.Salary
, CAST(DECRYPTBYKEY(e.EncryptedSalary) AS VARCHAR(50)) AS DecryptedSalary
, e.EncryptedSalary
 FROM dbo.Employees AS e
GO

What is returned in the DecryptedSalary column?

Answer: I get back NULL because the encryption process changed in SQL Server 2017

Explanation: The encryption process actually changed in SQL Server 2017. The encryption algorithm for the data is the same, but the way that the key values are hashed changed from SHA1 to SHA2. This means the data encrypted with symmetric keys need to be decrypted and re-encrypted with the new key when you change from a version prior to SQL Server 2017 to one later. Ref:
