(Perl) PBKDF1 - Derive Key from Password

Demonstrates how to derive a symmetric encryption key from a password using PBKDF1. This example matches the results found at this URL: http://www.di-mgt.com.au/cryptoKDFs.html#examplespbkdf

It also matches the output produced by the .NET Framework using this C# code:

            byte[] salt = new byte[] { 0x78, 0x57, 0x8E, 0x5A, 0x5D, 0x63, 0xCB, 0x06 };
            PasswordDeriveBytes cdk = new PasswordDeriveBytes("password", salt);

            cdk.IterationCount = 1000;
            cdk.HashName = "SHA1";

            // generate a 16-byte key
            byte[] key = cdk.GetBytes(16);
