Codes

[Young Bard]

Okay. Fairly simple rules. You post an encrypted code, the next person decrypts it, posts a new encrypted code (different message, different encryption) and the next person decrypts it, and so on.

 

E.g.

Post 1:

 

8 5 12 12 15 / 23 15 18 12 4

 

Post 2:

 

Hello World

 

b451c 1337

(the first code is just a letter-number conversion. The second one, though I didn't post the answer, uses something called leet speak.)

 

You get the picture.

 

So here's the first one.

Your other one says "basic leet"

 

Encoder

|1 3 3|

|1 4 3|

|1 3 4|

 

44  151  150  26  78  96  34  102  128  45  154  161  32  119  96  59  189  200  22  66  66

 

Hint:

|1 3 3|   | 7 -3 -3|   |1 0 0|

|1 4 3| x |-1  1  0| = |0 1 0|

|1 3 4|   |-1  0  1|   |0 0 1|

 

0 = {space}

Hint 2:

Encoder x Decoder = Identity Matrix

I used the Encoder to code my message but you need to use the Decoder to decode my message.

|1 0 0|

|0 1 0| = Identity Matrix

|0 0 1|

My message is then in another code that should be pretty easy to decode.

. . . What?

I am so bad at codes, so I'll just leave my ultra simple one here and the next person can solve both.
