Description

Cryptography can be easy, do you know what ROT13 is? cvpbPGS{arkg_gvzr_V'yy_gel_2_ebhaqf_bs_ebg13_uJdSftmh}

Solving

I know that this encryption shifts any character by 13 in the alphabet wheel So we gonna use tr

$ echo "cvpbPGS{arkg_gvzr_V'yy_gel_2_ebhaqf_bs_ebg13_uJdSftmh}" | tr "a-zA-Z" "n-za-mN-ZA-M"
picoCTF{next_time_I'll_try_2_rounds_of_rot13_hWqFsgzu}

Note

the flag contains lower and uppercase letters which means we must add this to the tr command
