sign() [1/2]

template<typename Curve >

void lime::bctbx_EDDSA< Curve >::sign ( const std::vector< uint8_t > &  message, DSA< Curve, lime::DSAtype::signature > &  signature  )

inlineoverridevirtual

Sign a message using the key pair previously set in the object.

Parameters

[in]	message	The message to be signed (we can sign any vector or more specifically a key exchange public key)
[out]	signature	The signature produced from the message with a key pair previously introduced in the object

Implements lime::Signature< Curve >.

sign() [2/2]

template<typename Curve >

void lime::bctbx_EDDSA< Curve >::sign ( const X< Curve, lime::Xtype::publicKey > &  message, DSA< Curve, lime::DSAtype::signature > &  signature  )

inlineoverridevirtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

a convenience function to directly verify a key exchange public key

Implements lime::Signature< Curve >.

verify() [1/2]

template<typename Curve >

bool lime::bctbx_EDDSA< Curve >::verify ( const std::vector< uint8_t > &  message, const DSA< Curve, lime::DSAtype::signature > &  signature  )

inlineoverridevirtual

Verify a message signature using the public key previously set in the object.

Parameters

[in]	message	The message signed (we can verify any vector or more specifically a key exchange public key)
[in]	signature	The signature produced from the message with a key pair previously introduced in the object

Returns

true if the signature is valid, false otherwise

Implements lime::Signature< Curve >.
