Project 05 - Obfuscation pt 1 - Steganography and Symmetric Encryption 🔐

Commands used (in the order that they appear in the video): Steghide tool 1. cd Desktop/Challenges/Steganography (changing directories) 2. eog clue.jpg (to view jpeg image will we try to find information in) 3. steghide extract -sf clue.jpg (to try and extract hidden data from image) 4. Enter password 5. cat hidden.txt (to view contents of data that was extracted and stored in text file) Symmetric encryption (each line of ciphertext is the word Cryptography encrypted in different symmetric algorithms, ls to show them and different modes) 6. cd ../Cryptography/Symmetric (to change directories again) 7. awk 'curved bracket print curved backet' * greater than sign salted.txt (to store the ciphertext of files in this directory to a text file) 8. cat salted.txt (to read the txt file that the ciphertext is stored in) OpenSSL (command line utility to generate private keys, encrypt, decrypt, create certificate signing requests, generate certificates, and identify certificate information) 9. openssl enc -d -des-ecb -in des-ecb.enc -out des-ecb.txt (to decrypt des ecb ciphertext) 10. Enter password 11. cat des-ecb.txt (to read the txt file that the clear text is stored in) 12. openssl enc -d -des-cbc -in des-cbc.enc -out des-cbc.txt (to decrypt des cbc ciphertext) 13. Enter password 14. cat des-cbc.txt 15. openssl enc -d -des-ede3-ecb -in 3des-ecb.enc -out 3des-ecb.txt (to decrypt 3des ecb ciphertext) 16. Enter password 17. cat 3des ecb ciphertext 18. openssl enc -d -des-ede3-cbc -in 3des-cbc.enc -out 3des-cbc.txt (to decrypt 3des cbc ciphertext) 19. Enter password 20. cat 3des-cbc.txt 21. openssl enc -d -aes-256-ecb -in aes-ecb.enc -out aes-ecb.txt (to decrypt aes ecb ciphertext) 22. Enter password 23. cat aes-ecb.txt 24. openssl enc -d -aes-256-cbc -in aes-cbc.enc -out aes-cbc.txt (to decrypt aes ecb ciphertext) 25. Enter password 26. cat aes-cbc.txt
