## Solution
Putting the given cipher text in [cipher identifier](https://www.dcode.fr/cipher-identifier), we get that the name of the cipher is `Trithemius Ave Maria`.
When we try to decrypt it, it gives us :
`RSTHISISTRITHEMIUS`
But this is not the final flag as the challenge says, it is case sensitive.
Changing the case sensitivity as per the given `cipher.txt`(If the case of the starting alphabet of the word is uppercase, we change the decypted alphabet to upper case as well).
By this change and and wrapping it with {}, we get:
`RS{ThIsIsTrItHeMiUs}`
