Detailed Description
Compute a SHA-256 message digest.
This class provides an interface to compute a digest in a "streaming" manner (the message can be split into chunks which are processed sequentially) as well as a convenient interface which allows one to create a digest in a single step.

void CS::Utility::Checksum::SHA256::Append | ( | const uint8 * | input, | |
size_t | length | |||
) |
Used to update the the input data hash.
- Parameters:
-
input A pointer to an array of the input data with which to update the hash. length The length of the input data to hash (in bytes).
static Digest CS::Utility::Checksum::SHA256::Encode | ( | const void * | , | |
size_t | nbytes | |||
) | [static] |
Encode a buffer.
static Digest CS::Utility::Checksum::SHA256::Encode | ( | const char * | ) | [static] |
Encode a null-terminated string buffer.
Digest CS::Utility::Checksum::SHA256::Finish | ( | ) |
Used to complete the hashing process and obtain the calculated hash.
After finishing, don't append further data to the hash -- the resulting digest will be bogus.
- Returns:
- The calculated hash.
