SE050 RSA OAEP mode support

Hi,

I'm trying to encrypt small pieces of data using RSA2048 key stored inside SE050. The SE050 is being access through MW v04.03.00. The requirement was to use RSA-OAEP mode with SHA256 digest. However, from experimentation, I only seem to be able to successfully encrypt anything by passing `kAlgorithm_SSS_RSAES_PKCS1_OAEP_SHA1`. Attempting to use any other digest results in 1010565120 (0x3c3c0000) status error. Can you confirm if this is a limitation of SE050?

Hi @bboozzoo ,

Yes, so far only SHA1 is supported for digest. Please kindly refer to the following for details.

Have a great day,
Kan
