Sha1 is not perfect, but even if its actual strength is closer to say 72 bits than its theoretical maximum strength (which is 80 bits for a 160 bit long hash), the odds of a collision are two small to worry about. You still talking about one chance in on the order of 100000000000000000000. The sha2 family does provide more bits. And whirlpool¹ seems to have consensus as the “best” choice currently available. But sha1 is still good enough for general use. -JimC 1] http://en.wikipedia.org/wiki/Whirlpool_(cryptography) http://planeta.terra.com.br/informatica/paulobarreto/WhirlpoolPage.html ISO/IEC 10118-3 http://www.incits.org/ref-docs/FDIS_10118-3.pdf -- James Cloos <[EMAIL PROTECTED]> OpenPGP: 1024D/ED7DAEA6 _______________________________________________ DBmail mailing list [email protected] https://mailman.fastxs.nl/mailman/listinfo/dbmail
