Detailed Description

raw key and signature access and conversion

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

Function Documentation

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
