SE050 RSA OAEP mode support

[bboozzoo]

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
