Functions
size_t	sldns_rr_dnskey_key_size_raw (const unsigned char *keydata, const size_t len, int alg)
	get the length of the keydata in bits
uint16_t	sldns_calc_keytag_raw (uint8_t *key, size_t keysize)
	Calculates keytag of DNSSEC key, operates on wireformat rdata.

Detailed Description

raw key and signature access and conversion

Since those functions heavily rely op cryptographic operations, this module is dependent on openssl.

sldns_rr_dnskey_key_size_raw()

size_t sldns_rr_dnskey_key_size_raw	(	const unsigned char *	keydata,
		const size_t	len,
		int	alg
	)

get the length of the keydata in bits

Parameters

[in]	keydata	the raw key data
[in]	len	the length of the keydata
[in]	alg	the cryptographic algorithm this is a key for

Returns

the keysize in bits, or 0 on error

sldns_calc_keytag_raw()

uint16_t sldns_calc_keytag_raw	(	uint8_t *	key,
		size_t	keysize
	)

Calculates keytag of DNSSEC key, operates on wireformat rdata.

Parameters

[in]	key	the key as uncompressed wireformat rdata.
[in]	keysize	length of key data.

Returns

the keytag
