/**
|
|
* Class Hasher provides some basic hashing functions. Furthermore, it supports legacy hashes
|
|
* used by previous versions of ownCloud and helps migrating those hashes to newer ones.
|
|
*
|
|
* The hashes generated by this class are prefixed (version|hash) with a version parameter to allow possible
|
|
* updates in the future.
|
|
* Possible versions:
|
|
* - 1 (Initial version)
|
|
*
|
|
* Usage:
|
|
* // Hashing a message
|
|
* $hash = \OC::$server->getHasher()->hash('MessageToHash');
|
|
* // Verifying a message - $newHash will contain the newly calculated hash
|
|
* $newHash = null;
|
|
* var_dump(\OC::$server->getHasher()->verify('a', '86f7e437faa5a7fce15d1ddcb9eaeaea377667b8', $newHash));
|
