The two strings are the same, but with the bytes (hex digit pairs) in reversed order (with an extra c at the beginning).  The first string starts with 24 6c 5a ... and the second string ends with ... 5a 6c 24.
It looks like an endianness flip to me (network order is big-endian, but  your machine is presumably using little-endian order).  I don't know what the meaning of the extra c is.
