You suspect that the /usr/bin/ls
binary on a system might have been replaced with a "Trojan
horse." You have been able to determine that the correct
MD5 checksum for the real /usr/bin/ls binary is: md5
(/usr/bin/ls) = b526348afd2d57610dd3635e46602d2a Which
standard Solaris command can be used to calculate the MD5
checksum for the /usr/bin/ls file?

A.
md5 /usr/bin/ls

B.
sum -r /usr/bin/ls

C.
sum -a md5 /usr/bin/ls

D.
crypt -a md5 /usr/bin/ls

E.
digest -a md5 /usr/bin/ls
