Detailed Description
Interface for domains of simple key agreement protocols.
A key agreement domain is a set of parameters that must be shared by two parties in a key agreement protocol, along with the algorithms for generating key pairs and deriving agreed values.

Member Function Documentation
◆ AgreedValueLength()
|
pure virtual |
Provides the size of the agreed value.
- Returns
- size of agreed value produced in this domain
Implemented in DL_SimpleKeyAgreementDomainBase< T >, DL_SimpleKeyAgreementDomainBase< GROUP_PARAMETERS::Element >, x25519, and XTR_DH.
◆ PrivateKeyLength()
|
pure virtual |
Provides the size of the private key.
- Returns
- size of private keys in this domain
Implemented in DL_SimpleKeyAgreementDomainBase< T >, DL_SimpleKeyAgreementDomainBase< GROUP_PARAMETERS::Element >, x25519, and XTR_DH.
◆ PublicKeyLength()
|
pure virtual |
Provides the size of the public key.
- Returns
- size of public keys in this domain
Implemented in DL_SimpleKeyAgreementDomainBase< T >, DL_SimpleKeyAgreementDomainBase< GROUP_PARAMETERS::Element >, x25519, and XTR_DH.
◆ GeneratePrivateKey()
|
pure virtual |
Generate private key in this domain.
- Parameters
-
rng a RandomNumberGenerator derived class privateKey a byte buffer for the generated private key in this domain
- Precondition
COUNTOF(privateKey) == PrivateKeyLength()
Implemented in DL_SimpleKeyAgreementDomainBase< T >, DL_SimpleKeyAgreementDomainBase< GROUP_PARAMETERS::Element >, x25519, and XTR_DH.
◆ GeneratePublicKey()
|
pure virtual |
Generate a public key from a private key in this domain.
- Parameters
-
rng a RandomNumberGenerator derived class privateKey a byte buffer with the previously generated private key publicKey a byte buffer for the generated public key in this domain
- Precondition
COUNTOF(publicKey) == PublicKeyLength()
Implemented in DH_Domain< GROUP_PARAMETERS, COFACTOR_OPTION >, DH_Domain< DL_GroupParameters_GFP_DefaultSafePrime >, DL_SimpleKeyAgreementDomainBase< T >, DL_SimpleKeyAgreementDomainBase< GROUP_PARAMETERS::Element >, x25519, and XTR_DH.
◆ GenerateKeyPair()
|
virtual |
Generate a private/public key pair.
- Parameters
-
rng a RandomNumberGenerator derived class privateKey a byte buffer for the generated private key in this domain publicKey a byte buffer for the generated public key in this domain
GenerateKeyPair() is equivalent to calling GeneratePrivateKey() and then GeneratePublicKey().
- Precondition
COUNTOF(privateKey) == PrivateKeyLength()-
COUNTOF(publicKey) == PublicKeyLength()
◆ Agree()
|
pure virtual |
Derive agreed value.
- Parameters
-
agreedValue a byte buffer for the shared secret privateKey a byte buffer with your private key in this domain otherPublicKey a byte buffer with the other party's public key in this domain validateOtherPublicKey a flag indicating if the other party's public key should be validated
- Returns
- true upon success, false in case of failure
Agree() derives an agreed value from your private keys and couterparty's public keys.
The other party's public key is validated by default. If you have previously validated the static public key, use validateStaticOtherPublicKey=false to save time.
- Precondition
COUNTOF(agreedValue) == AgreedValueLength()-
COUNTOF(privateKey) == PrivateKeyLength() -
COUNTOF(otherPublicKey) == PublicKeyLength()
Implemented in DL_SimpleKeyAgreementDomainBase< T >, DL_SimpleKeyAgreementDomainBase< GROUP_PARAMETERS::Element >, x25519, and XTR_DH.
