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 [Changcheng]: Built yet

how the isa-l crypto usage method in Ceph currently. [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.

Best wishes,

Shijin
