Detailed Description

template<class MAC, bool DHAES_MODE, bool LABEL_OCTETS = false>
class DL_EncryptionAlgorithm_Xor< MAC, DHAES_MODE, LABEL_OCTETS >

P1363 based XOR Encryption Method.

Template Parameters
MACMessageAuthenticationCode derived class used for MAC computation
DHAES_MODEflag indicating DHAES mode
LABEL_OCTETSflag indicating the label is octet count

DL_EncryptionAlgorithm_Xor is based on an early P1363 draft, which itself appears to be based on an early Certicom SEC-1 draft (or an early SEC-1 draft was based on a P1363 draft). Crypto++ 4.2 used it in its Integrated Ecryption Schemes with NoCofactorMultiplication, DHAES_MODE=false and LABEL_OCTETS=true.

If you need this method for Crypto++ 4.2 compatibility, then use the ECIES template class with NoCofactorMultiplication, DHAES_MODE=false and LABEL_OCTETS=true.

If you need this method for Bouncy Castle 1.54 and Botan 1.11 compatibility, then use the ECIES template class with NoCofactorMultiplication, DHAES_MODE=true and LABEL_OCTETS=false.

Bouncy Castle 1.54 and Botan 1.11 compatibility are the default template parameters.

Since
Crypto++ 4.0
