Function Documentation

signature_share_t* tc_node_sign	(	const key_share_t *	share,
		const bytes_t *	doc,
		const key_metainfo_t *	info
	)

Function that generates a signature share using a key share. A standard RSA signature is generated using several signature shares. The document to be signed should be prepared (hashed and padded) before using this function. In order to prepare the document we provide the tc_prepare_document function. But any other padder function may be used. For example, the Botan library provides a complete set of procedures that provide that functionality.

Parameters

[in]	share	the key share to be used in the signature operation.
[in]	doc	the document to be signed.
[in]	the	metainfo of the key shares array.

Returns

a signature share.
