DataPower HSM should support RSA-OAEP

The current HSM version in IDGx2 and IDGx3 does not support RSA OAEP padding which is a major issue as the only supported alternative is RSA1_5 (PKCS1-v1_5) which is considered vulnerable.

The decryption of an RSA-OAEP or RSA-OAEP-256 encrypted JWT fails in all cases where the private key for decryption is stored in the HSM.

Support of RSA OAEP and MGF algorithm for key management in HSM enabled devices

Merged
Currently DataPower with HSM module only support RSA1_5 as key management algorithm. The other asymmetric algorithms like RSA with OAEP. MFG is supported but only for XML encryption, not for JWE. RSA1_5 has known vulnerabilities and everyone in th...
