Need AES-CCM Support

[mjl0602]

I just see there is AES-GCM, cannot find AES-CCM.

As far as I know AES-CCM isn't supported. Is there a specific reason you must use AES-CCM? AES-GCM is considered superior over AES-CCM the reasons for this were greatly explained on this thread (https://crypto.stackexchange.com/questions/6842/how-to-choose-between-aes-ccm-and-aes-gcm-for-storage-volume-encryption) So unless you really have to use AES-CCM just use AES-GCM.

Because encrypt MCU of our hardware did not support AEC-GCM……

I try to use dart:ffi but there is memory problem always cause app crash.

At last ,in ios, I use C with OC. Android support AEC-CCM native so i can finally use AEC-CCM.

But I wish there is some better way to use AEC-CCM with dart code.

Thanks.
