HMAC * | CryptoLink::createHMAC (const void *, size_t, const HashAlgorithm) |
HMAC support.
This class is used to create and verify HMAC signatures. Instances can be created with CryptoLink::createHMAC()

isc::cryptolink::HMAC::~HMAC | ( | ) |
Destructor.

HashAlgorithm isc::cryptolink::HMAC::getHashAlgorithm | ( | ) | const |
Returns the HashAlgorithm of the object.

size_t isc::cryptolink::HMAC::getOutputLength | ( | ) | const |
Returns the output size of the digest.

void isc::cryptolink::HMAC::sign | ( | isc::util::OutputBuffer & | result, |
size_t | len ) |
Calculate the final signature.
The result will be appended to the given outputbuffer
LibraryError | if there was any unexpected exception in the underlying library |
result | The OutputBuffer to append the result to |
len | The number of bytes from the result to copy. If this value is smaller than the algorithms output size, the result will be truncated. If this value is larger, only output size bytes will be copied |

std::vector< uint8_t > isc::cryptolink::HMAC::sign | ( | size_t | len | ) |
Calculate the final signature.
The result will be returned as a std::vector<uint8_t>
LibraryError | if there was any unexpected exception in the underlying library |
len | The number of bytes from the result to copy. If this value is smaller than the algorithms output size, the result will be truncated. If this value is larger, only output size bytes will be copied |

void isc::cryptolink::HMAC::sign | ( | void * | result, |
size_t | len ) |
Calculate the final signature.
len bytes of data from the result will be copied to *result If len is larger than the output size, only output_size bytes will be copied. If it is smaller, the output will be truncated
LibraryError | if there was any unexpected exception in the underlying library |
At least len bytes of data must be available for writing at result

void isc::cryptolink::HMAC::update | ( | const void * | data, |
const size_t | len ) |
Add data to digest.
LibraryError | if there was any unexpected exception in the underlying library |
data | The data to add |
len | The size of the data |

bool isc::cryptolink::HMAC::verify | ( | const void * | sig, |
size_t | len ) |
Verify an existing signature.
LibraryError | if there was any unexpected exception in the underlying library |
sig | The signature to verify |
len | The length of the signature. If this is smaller than the output length of the algorithm, only len bytes will be checked. If this is larger than the output length of the algorithm, only output size bytes will be checked |
