Table of Contents
Interfaces
- HashInterface
- Interface that allows implementing various incremental hashes.
Constants
- EMPTY_HASH = 'e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855'
- MB = 1048576
Methods
- __construct() : mixed
- addChecksum() : self
- Add a checksum to the tree hash directly
- complete() : string
- Finalizes the incremental hash and returns the resulting digest.
- reset() : mixed
- Removes all data from the hash, effectively starting a new hash.
- update() : mixed
- Adds data to the hash.
