# Francis Bacon

{% file src="/files/3P72zuUid1Cel1sSg00M" %}

**Category:** Crypto - **Points:** 100 - **Solves:**\
**Description:**\
Decipher the hidden message!

**Solution:**\
To solve this challenge you need to decipher the flag in the [chal2](https://github.com/Ayweth20/HackDay_Qualifications/blob/main/Crypto/Francis%20Bacon/chal2) file.\
If we do a `file chal2` command, we can see that's an ASCII text file.\
To see the content file, we do `cat chal2` and this string is send back : *AAAABAAAAAAAABAABBABABBAAAAABAAAAAAABBAAAABABABAAABAAAAAABAABAABBABBBA*\
To find the string encryption, we can go on this [website](https://www.dcode.fr/identification-chiffrement)\
The [**Bacon Cipher**](https://www.dcode.fr/chiffre-bacon-bilitere) is detected and if we go on the website to decrypt this string the flag is decode.\
