**_Encryption Utility_**
We need an encryption utility that will use machine info as well as an encryption key hashed together to encrypt and decrypt a string. This must be written using the .net framework 1.1.
1. GetMachineInfo method needs to return the computer name and the hard drive serial number.
2. Decrypt method will use this machine info as well as a passed in encryption key together to hash its own internal encryption key and return a decrypted string.
3. Encrypt method will use this machine info as well as a passed in encryption key together to hash its internal encryption key and return a encrypted string.
Function Descriptions:
GetMachineInfo()
Get the computer name and hard drive serial number and return those two strings concatenated together.
Decrypt( EncryptionKey, String )
Retrieve the Machine Info and the Encryption key. Hash these together, decrypt and return the decrypted string.
Encrypt( EncryptionKey, String )
Retrieve the Machine Info and the Encryption key. Hash these together, encrypt and return the encrypted string.
