SHA-256 secure hash generator.
Create one of these objects from a block of source data or a stream, and it calculates the SHA-256 hash of that data.
You can retrieve the hash as a raw 32-byte block, or as a 64-digit hex string.

juce::SHA256::SHA256 | ( | ) |
Creates an empty SHA256 object.
The default constructor just creates a hash filled with zeros. (This is not equal to the hash of an empty block of data).
juce::SHA256::~SHA256 | ( | ) |
Destructor.
|
explicit |
Creates a hash from a block of raw data.
juce::SHA256::SHA256 | ( | const void * | data, |
size_t | numBytes | ||
) |
Creates a hash from a block of raw data.
juce::SHA256::SHA256 | ( | InputStream & | input, |
int64 | maxBytesToRead = -1 |
||
) |
Creates a hash from the contents of a stream.
This will read from the stream until the stream is exhausted, or until maxBytesToRead bytes have been read. If maxBytesToRead is negative, the entire stream will be read.
|
explicit |
Reads a file and generates the hash of its contents.
If the file can't be opened, the hash will be left uninitialised (i.e. full of zeros).

MemoryBlock juce::SHA256::getRawData | ( | ) | const |
Returns the hash as a 32-byte block of data.

String juce::SHA256::toHexString | ( | ) | const |
Returns the checksum as a 64-digit hex string.
