MD5 is not fips compliant. Hence replacing with SHA256. NOTE: The hash is used to form the ctl_path for the ssh connection. The length of ctl_path for ssh connection should not be > 108. ssh fails with ctl_path too long if it is so. But when rsync is piped to ssh, it is not taking > 90. rsync is failing with error number 12. Hence using first 32 bytes of hash. Hash collision doesn't matter as only one sock file is created per directory. Change-Id: I58aeb32a80b5422f6ac0188cf33fbecccbf08ae7 Updates: #230 Signed-off-by: Kotresh HR <khiremat@redhat.com>
