Hello Bro, can you assist me on MSS Crypto

Ok look into rivest Shamir secret sharing in python.

Basically, you split a secret into a given number of parts (n) and define a threshold (t) for how many parts are needed to get the secret.

You can ask for enough shares to get the key

I will appreciate if you can explain more, do we have to use https://github.com/adviksinghania/shamir..._secret.py and how ?

i got the 

Encrypted Flag
"iv": "22e159b91af7be16edd895ab3f021778", "enc_flag": "8125fc9c7793a1f0a0b3bf85fd9b5ad7cf828e12f72c2edbacc98d9970c77a31cc1ecd53e9dd3ff4c5e5673219deaabe"}

Share
{"approved": "True", "x": 1, "y": 1672688893529867488399516862618660024526966971847006494677454708922044545978349}


and once after getting all those information.. how do we exploit it ?
