Learning Cryptography & Cryptanalysis
#1
Learning Cryptography & Cryptanalysis By Solving This challenge Below .This is originally made by Th3PyRATwho is member & sexy cookie @ic0de.ws he couldn't post. So  posting it on his behalf.
@ic0de we where discussing to make general CTF. Th3PyRAT came with a idea of make this introductory CTF to Cryptography. we focused to make it
beginner friendly so more beginners happen to join ic0de.

how to participate in challenge below ?

Well it is simple decode all the Encode stuff.And post the Decode text here\

1)
Code:
110001 110000 1000010 1101001 1101110 1100001 1110010 1111001 110000 110001
Hint: this is often used by computers.

2)
Code:
65 108 108 52 79 110 101 38 79 110 101 52 65 108 108
Hint : American Standard ......................

3)
Code:
... .- ... -.- .. .- 
Hint: this code made by Samuel F. B. Morse

4)
Code:
UkFORE9NV09SRFNtYUtlWW9VRkVFbFdhVGVyRmFsTGluZ0FOZFBob2VOaXg==
Hint: look at the == sign b4se*4

5)
Code:
JFRWQIDLN5WW2ZJAMF2XGICSYO6G2YLONFSW4LQ=
Hint: this is  32 chars of base

6)
Code:
69 50 68 6F 6E 65 20 69 73 20 6E 6F 74 20 67 6F 6F 64
Hint : Hex

7)
Hint: zago big

8)
Code:
Alpha Romeo Mike Yankee  Echo November Charlie Oscar Delta India November Golf  Sierra Echo Mike Papa Echo Romeo  Foxtrot India
Hint: Nato code

9)
Code:
ebg13 sbe vp0qr.jf qrpbqrq
Hint: ROT encryption guess the rotation key to decode this

10 )
Code:
22edc04c886cccd8368914f35d1f0991
Hint: looks like simple MD5 Hash



Enough of easy challenges time for something fun haha.The next  2 challenge will be mix of two or more encoding techniques

11)
Code:
5A47566A6232526C5A4342306147556764475634644342696232393559513D3D 
Hint: HEx encode goes to something very easy

12 )
Code:
4c 53 30 67 4c 53 30 74 49 43 34 74 4c 69 41 75 4c 69 34 67 4c 67 6f 74 4c 69 30 75 49 43 30 74 4c 53 41 74 4c 69 34 67 4c 67 6f 74 4c 69 30 75 49 43 34 74 4c 69 41 75 4c 53 41 74 4c 69 30 75 49 43 30 75 4c 53 41 75 49 43 30 75 4c 67 6f 3d

Well TBH this really interesting way to understand how cryptography works. Decoded few of them I'll work on them tomorrow need some sleep
1) 10Binary01 flag
2) All4One&One4All
3) SASKIA
4) RANDOMWORDSmaKeYoUFEElWaTerFalLingANdPhoeNix
