Detailed Description

Constructs a mechanism parameter for PKCS#1, v2.1 RSAES-PSS signature creation / verification padding scheme.

The following example illustrates the usage of the MechParamPSS class:

// sign data with PSS padding scheme
 
int mech = CXI_MECH_PAD_PSS | CXI_MECH_HASH_ALGO_SHA256;
 
MechParamPSS mechParam = MechParamPSS(mech, CXI_MECH_HASH_ALGO_SHA256, 16);
 
ByteArray sign = cxi->sign(0, rsaKey, mechParam.getEncoded(), data);
