SHA-1 byl vyvinut v roce 1995 a byl schv\u00e1len jako feder\u00e1ln\u00ed standard pro zpracov\u00e1n\u00ed informac\u00ed (FIPS 180-1), kter\u00fd umo\u017enil pou\u017eit\u00ed tohoto algoritmu ve vl\u00e1dn\u00edch instituc\u00edch USA. V roce 2005 byla prok\u00e1z\u00e1na teoretick\u00e1 mo\u017enost \u00fatoku na SHA-1. V roce 2017 byla pro SHA-1 demonstrov\u00e1na prvn\u00ed praktick\u00e1 kolizn\u00ed \u00fatok s dan\u00fdm prefixem, kter\u00fd umo\u017e\u0148uje pro dva r\u016fzn\u00e9 soubory naj\u00edt dodatky, jejich\u017e p\u0159ipojen\u00ed povede k vzniku kolize a vytvo\u0159en\u00ed stejn\u00e9ho v\u00fdsledn\u00e9ho hash (nap\u0159\u00edklad pro dva existuj\u00edc\u00ed dokumenty lze vypo\u010d\u00edtat dva dodatky a pokud jeden p\u0159ipoj\u00edme k prvn\u00edmu dokumentu a druh\u00fd k druh\u00e9mu, v\u00fdsledn\u00e9 hashe SHA-1 pro tyto soubory budou toto\u017en\u00e9). <\/p>\n
