router_append_dirobj_signature()

int router_append_dirobj_signature	(	char *	buf,
		size_t	buf_len,
		const char *	digest,
		size_t	digest_len,
		crypto_pk_t *	private_key )

Helper: used to generate signatures for routers, directories and network-status objects. Given a digest in digest and a secret private_key, generate a PKCS1-padded signature, BASE64-encode it, surround it with --—BEGIN/END--— pairs, and write it to the buf_len-byte buffer at buf. Return 0 on success, -1 on failure.

router_get_dirobj_signature()

char * router_get_dirobj_signature	(	const char *	digest,
		size_t	digest_len,
		const crypto_pk_t *	private_key )

Helper: used to generate signatures for routers, directories and network-status objects. Given a digest_len-byte digest in digest and a secret private_key, generate an PKCS1-padded signature, BASE64-encode it, surround it with --—BEGIN/END--— pairs, and return the new signature on success or NULL on failure.
