Good job! You did it!
Decode this mono-alphabetic cipher:
NMZ OEPYQJ GOOGOOPUGNPYU LGFZO GSZ G OZSPZO YK LGFZO PU CMPEM YUZ BOZS PO EMYOZU GO NMZ 'OGOOJ', CMY NMZU NSPZO NY APQQ XZYXQZ RJ XYONPUL EQBZO.

Hint: O=S
"Blessed are you when people insult you and persecute you, and falsely say all kinds of evil against you because of Me. Rejoice and be glad, for your reward in heaven is great; for in the same way they persecuted the prophets who were before you." Matthew 5:11-12

I have no regrets.

I think the decryption matrix is PBYF

Wait, shouldn’t the decryption matrix be four numbers?

I got this by creating two marices using "test" and "bzet," inverting one of the matrices, and multiplying the two matrices together

Yeah I did the same thing but I got
|15  1|
|24  5| or PBYF as my decryption matrix. I got 
|21  2|
|3  25| by multiplying BZET by the inverse of TEST as well, but that would give you the encryption matrix, right? So I inverted that to get my final answer. I may have interpreted the question incorrectly, sorry about that.

which is what I meant by PBYF, sorry for being unclear.
Encoding bzet with your matrix results in OTBJ
Encoding bzet with 21 2 3 25 results in TEST

Sorry yeah I just edited my answer. I found the same encryption matrix as you, but I thought you asked for the decryption matrix so I inverted it and gave that as my answer.

It would be the decryption maxtrix as it encrypts the cipher text into the plaintext, not vice versa.
Anyways your turn
