Detailed Description

HMAC-SHA256 secret key.

Member Function Documentation

getMaxSigLen()

size_t ndnph::HmacKey::getMaxSigLen ( ) const

inlinefinalvirtual

Implements ndnph::PrivateKey.

import()

bool ndnph::HmacKey::import ( const uint8_t *  key, size_t  keyLen  )

inline

Import raw secret key bits.

Parameters

key	raw key bits; will be copied if necessary.
keyLen	key length in octets.

Returns

whether success.

operator bool()

ndnph::HmacKey::operator bool ( ) const

inlineexplicit

Determine if this key is non-empty.

sign()

ssize_t ndnph::HmacKey::sign ( std::initializer_list< tlv::Value >  chunks, uint8_t *  sig  ) const

inlinefinalvirtual

Perform signing.

Parameters

	chunks	signed portion.
[out]	sig	signature buffer, with getMaxSigLen() room.

Returns

signature length, or -1 upon failure.

Implements ndnph::PrivateKey.

verify()

bool ndnph::HmacKey::verify ( std::initializer_list< tlv::Value >  chunks, const uint8_t *  sig, size_t  sigLen  ) const

inlinefinalvirtual

Perform verification.

Return values

true	signature is correct.
false	error or signature is incorrect.

Implements ndnph::PublicKey.
