Encryption Key Retrieval

This program will highlight the versatility of python by using many methods to accomplish a useful task. I plan to accept a 16-byte string that is entered by the user, return a cipher-text version that is unreadable, and then through the use of a key that has been retrieved from a Hardware Security Module display the unencrypted version.

Implementation

1. Create file ptext.txt with 16 bytes of information.
   • This will be input from the user
2. Establish SSL connection to HSM.
3. Upload ptext.txt for encryption
4. Create a symmetrical key.
5. Demonstrate that ptext.txt is encrypted and also show decrypted version.
   • concatenate ptext.txt
   • concatenate ctext.txt [the encrypted version]
   • give the user a chance to guess the key
   • show the encryption key that was used
