Public Functions¶

	Name
virtual std::vector< std::uint8_t >	EncryptData(std::vector< std::uint8_t > data, std::vector< std::uint8_t > key_data) override Encrypts a vector of data using the session secret.
virtual std::vector< std::uint8_t >	DecryptData(std::vector< std::uint8_t > data, std::vector< std::uint8_t > key_data) override Decrypts a vector of data using the session secret.
virtual bool	CheckEqual(const Encryption & lhs, const Encryption & rhs) const override Checks if two ECDHEncryption instances are equal.

Public Functions Documentation¶

function EncryptData¶

inline virtual std::vector< std::uint8_t > EncryptData(
    std::vector< std::uint8_t > data,
    std::vector< std::uint8_t > key_data
) override

Encrypts a vector of data using the session secret.

Parameters:

data Vector of data to be encrypted
key_data Unused in this implementation

Return: Encrypted data vector

Reimplements: Encryption::EncryptData

function DecryptData¶

inline virtual std::vector< std::uint8_t > DecryptData(
    std::vector< std::uint8_t > data,
    std::vector< std::uint8_t > key_data
) override

Decrypts a vector of data using the session secret.

Parameters:

data Vector of data to be decrypted
key_data Unused in this implementation

Return: Decrypted data vector

Reimplements: Encryption::DecryptData

function CheckEqual¶

inline virtual bool CheckEqual(
    const Encryption & lhs,
    const Encryption & rhs
) const override

Checks if two ECDHEncryption instances are equal.

Parameters:

lhs First instance of Encryption to be downcasted
rhs Second instance of Encryption to be downcasted

Return: true if session secrets are equal, false otherwise

Reimplements: Encryption::CheckEqual

function ECDHEncryption¶

inline ECDHEncryption(
    const nil::crypto3::pubkey::ext_private_key< PolicyType > & own_key,
    const nil::crypto3::pubkey::public_key< PolicyType > & foreign_key
)

Constructs an ECDHEncryption object and creates a session secret.

Parameters:

own_key The owner's private ECDSA key
foreign_key The other party's public key
