Hi all,
I'm focusing on the ISA-L encryption in the Ceph master. But when I read the
'CMakelists.txt' in Ceph, I found the default usage of crypto lib is
'openssl' rather than 'isa-l' or others.
So I just wonder whether the isa-l crypto has been built in Ceph and how the isa-l crypto
usage method in Ceph currently.
Hope you may help and reply. Thanks.
Best wishes,
Shijin

[Changcheng]:
It seems that src/crypto/{isa-l,openssl,qat} is only used in rgw:
https://github.com/ceph/ceph/blob/master/src/rgw/rgw_crypt.cc#L35
API: cbc_encrypt & cbc_decrypt
There's below option to select the plugin(default is isa-l):
https://github.com/ceph/ceph/blob/master/src/common/options.cc#L808
Hope you may help and reply. Thanks.
