Detailed Description

signature stream buffer.

Constructor & Destructor Documentation

Signaturebuf() [1/3]

Signaturebuf::Signaturebuf

(

const std::string &

algo

)

create the signature stream buffer instance.

Parameters

algo	the message digest used.

Signaturebuf() [2/3]

join::Signaturebuf::Signaturebuf ( const Signaturebuf & other )

delete

copy constructor.

Parameters

other

other object to copy.

Signaturebuf() [3/3]

join::Signaturebuf::Signaturebuf ( Signaturebuf && other )

default

move constructor.

Parameters

other

other object to move.

~Signaturebuf()

virtual join::Signaturebuf::~Signaturebuf ( )

virtualdefault

destroy the signature stream buffer instance.

Member Function Documentation

operator=() [1/2]

Signaturebuf & join::Signaturebuf::operator= ( const Signaturebuf & other )

delete

copy assignment operator.

Parameters

other

other object to assign.

Returns

current object.

operator=() [2/2]

Signaturebuf & join::Signaturebuf::operator= ( Signaturebuf && other )

default

move assignment operator.

Parameters

other

other object to assign.

Returns

current object.

sign()

BytesArray Signaturebuf::sign

(

const std::string &

privKey

)

sign with the given private key.

Parameters

privKey

path to private key.

Returns

the generated signature on success, an empty bytes array on failure.

verify()
