SecretKeySubmissionTemplate.docxCrypto Lab: Secret Key Encryption Submission Template
This is the template to be used when completing and submitting the Secret Key cryptography lab.
Monoalphabetic Substitution Cipher
The decrypted secret message was:
<insert the decrypted message here>
The secret key used to decrypt this message was:
<insert your secret key here>
Different Ciphers and Modes
The specific commands used for all 3 cipher modes for both encrypting and decrypting the file were:
<Ciphermode 1 Encryption command>
<Ciphermode 1 Decryption command>
<Ciphermode 2 Encryption command>
<Ciphermode 2 Decryption command>
<Ciphermode 3 Encryption command>
<Ciphermode 3 Decryption command>
Labeled screen captures showing the results for both encrypting and decrypting the file.
<Ciphermode 1 Encryption screen capture results >
<Ciphermode 1 Decryption screen capture results >
<Ciphermode 2 Encryption screen capture results >
<Ciphermode 2 Decryption screen capture results >
<Ciphermode 3 Encryption screen capture results >
<Ciphermode 3 Decryption screen capture results >
Initial Vectors
Describe and show your simple text file used as input.
<your results>
Provide the specific commands you used to encrypt your file
<your results>
Compare and describe the output between when the same ivs and different ivs are used. Think like a hacker. What patterns do you see that could help break the code?
<your results>
Explain why the iv needs to be unique
<your results>
