Digital Preservation Q&A - Recent questions tagged algorithms https://qanda.digipres.org/tag/algorithms Powered by Question2Answer To what extent do cryptographic hash (MD5, SHA1, etc.) collisions rates matter for fixity checking? https://qanda.digipres.org/13/extent-cryptographic-collisions-rates-matter-fixity-checking <h1 style="margin: 0px 0px 20px; line-height: 1.1; font-size: 28px; font-family: Lato, 'Helvetica Neue', Helvetica, Arial, sans-serif;"> <span style="font-size:12px;">Given the probabilities of hash value collisions are MD5 hashes sufficient for ensuring file fixity? Or should SHA1 or SHA2 be used? Or, should folks be catching all three. I would be interested in both issues to consider for tamper resistance and for simply knowing if what I have is what I think I have.</span></h1> https://qanda.digipres.org/13/extent-cryptographic-collisions-rates-matter-fixity-checking Mon, 03 Mar 2014 19:48:04 +0000
