Trying to match md5sum result with rpm -ql --dump

Trying to check the difference between the current MD5 checksum with the reported digest value from rpm on a specific file.

As an example:
/lib64/ld-2.17.so
Digest field from the --dump: 5dd05366a881b2c3c525beb5f6811f3584ff8b1de3c08ea79ae9bb54ffacf835

md5sum: 948e34b6b30f4642b0f071d8c946a061

My guess is that the digest field may not be what I am looking for, but I don't know what else it would be.

Any hints welcome.
