Detailed Description

A base class for classes providing hash functions.

Method Documentation

+ (size_t) blockSize

Returns the block size of the hash, in bytes.

Returns

The block size of the hash, in bytes

+ (size_t) digestSize

Returns the digest size of the hash, in bytes.

Returns

The digest size of the hash, in bytes

+ (instancetype) hash

Creates a new hash.

Returns

A new autoreleased OFHash

Reimplemented from <OFObject>.

- (BOOL) isCalculated

Returns a boolean whether the hash has already been calculated.

Returns

A boolean whether the hash has already been calculated

- (uint8_t*) OF_RETURNS_INNER_POINTER

- (void) updateWithBuffer:		(const void*)	buffer
length:		(size_t)	length

Adds a buffer to the hash to be calculated.

Parameters

buffer	The buffer which should be included into the calculation
length	The length of the buffer
