-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi,
I don't meant to change the hash funktion from SHA-1 to SHA-256, I meant to hash the 100 KB blocks and the higher level hashes with SHA-1 and to provide a SHA-256 hash that is generated from the file itself too. Because two hashes are more secure than one, even if one of them is broken, because if someone can find a collision in one hash he can't find a collision in the second at the same time. The two hash method is only mode secure than a single hash, if someone can't reverse calculate an information out of the hash. But SHA-1 is so far I know only vulnarable to collisions at some specific conditions. Maybe it will be mode secure to use RIPE-MD 160 for hashing the tree hashes and provide a SHA-256 hash for the whole file too. - -- SecTech <t...@firemail.de> GPG-ID: 0x364CFE05 -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJUrrZXAAoJENR4jiM2TP4FMbQP/jg8gBN+5xiSrx7rVOn/EvEl OLzEUsrOwNWZ2nbDz2GRMWTRmieBxRxnpp8IYkWjVry7h2hEkfAGTWTF1zlj5KPJ wNHxBb6Mlw9vlW79nnEdtgkANHgnlrxG/Gg0OYfV8YYquf5OMHvkXVwhv02U4sSr NxpIFTCg98gXX5297Prn5Ro/n1IECmJuCnh2+qNMB0GdZSwPB3L210/nltkhGcBI QV1jHc/AevLD4/QgdtV3iYmAHrIrmJ1wdXrlTMQXmmjQcuKL5keFBFXyWjwLBJeW RO/SK+ph6WCIQrl9CZds3VNvDdR42gb8H8JftGUJv5hyEgiWTfnyD5tCFKi2XBg2 WzzZ+1kebeO0BDTZupgKQqwPc4aG/YrThk3EIX+YJ0vDqIyweTU01SLvapZ/TVS2 zqfroqZTJ43i1j/s275fUyQohUuPlAsViVLt3sOY/REfHwxxYfiiLrp8IEuZWRlT w6jFxEwvao8o2UJXJ/fFsnJZG47JoXXTcNA8jvNxEqdzzCVrDFm3yWj+ftO+KxsI nMrdAkvYEG3K7prw+5RY9RvSeRh7WSaaOfcTBFtk5S4d/dWwknTSgN4uFksgvbdy dMrWNcBXPinLC6YNjKZZ6dTYll13jtC+RwuSmkjDjeOV6PWyiunyr6n6zP5tVZ4j bGH914P8fcG3+mVuvLK6 =y6wA -----END PGP SIGNATURE----- -- tor-talk mailing list - tor-talk@lists.torproject.org To unsubscribe or change other settings go to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
