Same as [Easy RSA](https://ctftime.org/writeup/28876), but have to work out p, q, from n. Just used [factordb to do the factoring](http://factordb.com/index.php?query=947358141650877977744217194496965988823475109838113032726009)...

```
p: 884666943491340899394244376743
q: 1070864180718820651198166458463
e: 65537
ct (as hex): 8159e4e97b04af127fed8fbd40bd03c80c3f4b8b764a86394c
n: 834418746183915656610879248898026819357498357797104542136881

pt (as hex): 6263616374667b7273615f666163746f72696e677d
pt (as string): bcactf{rsa_factoring}
```

Flag: `bcactf{rsa_factoring}`
