Detailed Description

Constructs a mechanism parameter that can be used on RSA encryption operations with the PKCS#1, v2.1 RSAES-OAEP encryption / decryption padding scheme.

The following example illustrates the usage of the MechParamOAEP class:

// encrypt data with OAEP padding scheme
 
int mech = CXI_MECH_MODE_ENCRYPT | CXI_MECH_PAD_OAEP | CXI_MECH_HASH_ALGO_SHA256;
 
MechParamOAEP mechParam = MechParamOAEP(mech, CXI_MECH_HASH_ALGO_SHA256, "MyLabel");
 
ByteArray crypt = cxi->crypt(0, rsaKey, mechParam.getEncoded(), data);

Constructor & Destructor Documentation

MechParamOAEP()

MechParamOAEP	(	int	mech,
		int	mgf_algo,
		const std::string &	label
	)

Constructs a mechanism specifier and parameter for PKCS#1, v2.1 RSAES-OAEP encryption / decryption padding scheme.

Parameters
