Detailed Description
template<typename T, T t_h0, T t_h1, T t_h2, T t_h3, T t_h4, T t_h5, T t_h6, T t_h7, size_t t_len>
class icl_core::crypt::Sha2< T, t_h0, t_h1, t_h2, t_h3, t_h4, t_h5, t_h6, t_h7, t_len >
An implementation of SHA-2, following the FIPS PUB 180-3 Secure Hash Standard (SHS).
Instead of instantiating this manually, use the convenience typedefs Sha224, Sha256, Sha384 or Sha512 instead.
Usage example (using Sha256):
Sha256 sha;
sha.process("An example string.");
sha.process("More data for the same digest.");
sha.finalize();
std::cout << sha.getHexDigest() << std::endl;
- Template Parameters
-
T The type of the message words (uint32_t or uint64_t). t_h0 The initial hash value, word 0. t_h1 The initial hash value, word 1. t_h2 The initial hash value, word 2. t_h3 The initial hash value, word 3. t_h4 The initial hash value, word 4. t_h5 The initial hash value, word 5. t_h6 The initial hash value, word 6. t_h7 The initial hash value, word 7. t_len The length, in words, of the message digest. This may be at most 8 (i.e., all eight words of the digest are used). Only the first t_len words of the digest are returned otherwise.
