I need your help to solve this cryptography challenge. Here are some steps to follow:

1. Identify the type of encryption or encoding used based on the challenge description and any provided files. Common types include:
- Classical ciphers (Caesar, Vigenère, substitution, etc.) 
- Modern symmetric ciphers (AES, DES, etc.)
- Asymmetric cryptography (RSA, ECC, etc.)
- Hashes and password cracking
- Encoding schemes (Base64, hex, etc.)

2. If there are any encrypted messages or ciphertexts, paste them here. Also include any keys, IVs, or other relevant parameters.

3. Analyze the encryption for weaknesses. Look for:
- Weak keys or poor randomness
- Use of insecure modes like ECB
- Oracles that leak information 
- Flaws in custom encryption schemes
- Reused one-time pads or nonces
- Hash length extension attacks

4. Attempt to decrypt the message:
- Brute-force attack if key space is small
- Frequency analysis and cribs for classical ciphers
- Exploit mathematical weaknesses of RSA
- Crack hashes with wordlists/rules/masks
- Abuse padding oracle vulnerabilities

5. If you successfully decrypt, the flag format is usually `flag{...}`. Submit that to the scoring system.

Let me know if you need any other information to solve the challenge! Cryptography can be tricky.
