Hi,
i am new to openssl and trying to add support for CTR mode in AES.
i dont know what i am doing is correct or not?
I made some changes based on my understanding but i want to cross verify.
For adding the above support, first i need to add SN_LN,NID, OBJ etc for CTR
mode just like AES in CBC (SN_aes_128_cbc,LN_aes_128_cbc,..) mode.
For adding the mentioned (SN, LN, NID, OBJ), i did the following change.
1. I added the follwoing line in objects.txt
"aes 6 : AES-128-CTR : aes-128-ctr"
2. then i execuated the command mentioned in the objects.pl to create
obj_mac.h from objects.txt
perl objects.pl objects.txt obj_mac.num obj_mac.h
3. Then i execuated following command to obj_dat.h from obj_mac.h
perl obj_dat.pl obj_mac.h obj_dat.h
I also want to know that can i add nids or not?
If i can, then is the above method is correct or not ?
And also i added above line with aes 6, because i found that upto aes 5 it was
already there. Is it correct ?
If i am wrong, please correct me and explain me the correct method.
And also share any documentation which can help me in adding above support.
Thanks in advance,
Regards
Rakesh
