Code comparison

Not applicable for these repositories, as they primarily consist of markdown files and don't contain significant code samples.

Key differences

write-ups-2014:

• Focuses on detailed write-ups for specific CTF challenges from 2014
• Provides step-by-step solutions and explanations
• Organized by individual CTF events

awesome-ctf:

• Curated list of tools, resources, and learning materials for CTF participants
• Covers a wide range of topics including cryptography, forensics, and web exploitation
• Includes links to practice platforms and CTF event listings

Use cases

write-ups-2014:

• Ideal for those looking to learn from past CTF challenges
• Useful for understanding specific techniques used in 2014 CTFs

awesome-ctf:

• Great starting point for newcomers to CTF competitions
• Valuable resource for experienced participants looking for new tools and learning materials
• Helps in preparing for various types of CTF challenges

Pros of write-ups-2015

• More comprehensive coverage of CTF events
• Improved organization and structure of write-ups
• Increased community contributions and participation

Cons of write-ups-2015

• Potentially overwhelming amount of information for newcomers
• Some write-ups may lack detailed explanations or context

Code Comparison

write-ups-2014:

def decrypt(ciphertext, key):
    return ''.join(chr(ord(c) ^ key) for c in ciphertext)

write-ups-2015:

def decrypt(ciphertext, key):
    plaintext = ""
    for i in range(len(ciphertext)):
        plaintext += chr(ord(ciphertext[i]) ^ ord(key[i % len(key)]))
    return plaintext

The code in write-ups-2015 shows a more advanced decryption function that uses a repeating key, whereas the write-ups-2014 version uses a single-byte XOR operation. This demonstrates the progression in complexity and sophistication of challenges and solutions between the two years.

Both repositories serve as valuable resources for CTF participants, offering insights into various challenges and solution techniques. The write-ups-2015 repository builds upon the foundation laid by its predecessor, providing a more extensive collection of write-ups and reflecting the evolving nature of CTF competitions.

Pros of write-ups-2016

• More recent and up-to-date CTF challenges and solutions
• Larger community contribution due to increased popularity of CTFs
• Improved organization and structure of write-ups

Cons of write-ups-2016

• Potentially overwhelming amount of information for beginners
• Some older, classic challenges may not be included
• Possibly less detailed explanations in some write-ups due to time constraints

Code Comparison

write-ups-2014:

def decrypt(ciphertext, key):
    plaintext = ""
    for i in range(len(ciphertext)):
        plaintext += chr(ord(ciphertext[i]) ^ ord(key[i % len(key)]))
    return plaintext

write-ups-2016:

from Crypto.Cipher import AES
def decrypt(ciphertext, key):
    cipher = AES.new(key, AES.MODE_ECB)
    return cipher.decrypt(ciphertext)

The code comparison shows a shift from simple XOR-based encryption in 2014 to more advanced cryptographic libraries like AES in 2016, reflecting the increasing complexity of CTF challenges over time.

Pros of write-ups-2017

• More recent and up-to-date CTF challenges and solutions
• Larger community contribution due to increased popularity of CTFs
• Improved organization and structure of write-ups

Cons of write-ups-2017

• Potentially overwhelming amount of information for beginners
• Some older, classic challenges may not be included
• Possibly less detailed explanations in some write-ups due to time constraints

Code Comparison

write-ups-2014:

def decrypt(ciphertext, key):
    plaintext = ""
    for i in range(len(ciphertext)):
        plaintext += chr(ord(ciphertext[i]) ^ ord(key[i % len(key)]))
    return plaintext

write-ups-2017:

from Crypto.Cipher import AES
from Crypto.Util.Padding import unpad

def decrypt(ciphertext, key):
    cipher = AES.new(key, AES.MODE_ECB)
    return unpad(cipher.decrypt(ciphertext), AES.block_size)

The code comparison shows an evolution in cryptographic techniques used in CTF challenges. The 2014 example uses a simple XOR cipher, while the 2017 example employs the more advanced AES encryption algorithm, reflecting the increased complexity of modern CTF challenges.
