HashPass - SQL

HashPass - SQL is a package that provides an easy way for SQL developers to generate hashed passwords in their applications. It is implemented in SQL and supports a variety of hash algorithms including MD5, SHA1, SHA2, and bcrypt.

Installation

To install HashPass - SQL, you can download the SQL script from the official GitHub repository and execute it in your SQL Server Management Studio. Alternatively, you can use a package manager such as NuGet or Chocolatey to install it.

Usage

Here's an example of how to use HashPass - SQL to generate a hashed password:

DECLARE @password NVARCHAR(100) = 'myPassword123'
DECLARE @salt NVARCHAR(100) = 'mySalt'

-- generate a MD5 hash
SELECT dbo.hashpass_md5(@password, @salt) AS 'Hashed Password'

-- generate a SHA1 hash
SELECT dbo.hashpass_sha1(@password, @salt) AS 'Hashed Password'

-- generate a SHA2 hash
SELECT dbo.hashpass_sha2(@password, @salt, 256 /* SHA2-256 */) AS 'Hashed Password'
SELECT dbo.hashpass_sha2(@password, @salt, 512 /* SHA2-512 */) AS 'Hashed Password'

-- generate a bcrypt hash
SELECT dbo.hashpass_bcrypt(@password, @salt) AS 'Hashed Password'

Security Considerations

When using HashPass - SQL to store hashed passwords, it's important to adhere to best practices for password storage, such as:

• Using a secure hashing algorithm such as bcrypt, which is designed specifically for password hashing.
• Adding a unique salt to each password before hashing to prevent attackers from using precomputed hash tables.
• Iterating the hash function multiple times (known as key stretching) to slow down attackers who may attempt to crack stored passwords.

Conclusion

HashPass - SQL is a useful package for SQL developers who need an easy way to generate and store hashed passwords in their applications. By following best practices for password storage, you can help ensure that your users' passwords remain secure even in the event of a data breach.
