[REBOL] checksum/secure

From: allen::rebolforces::com at: 30-Aug-2000 10:44

Hi REBOL's, checksum/secure was added in core v2.3, but wasn't documented in the release notes. So for all those curious about it, here are some notes from Bo. ;--------- CHECKSUM/SECURE is based on SHA1. MD5 is no longer considered to be completely secure and SHA1 is the successor. Here is the REBOL- computed probability of two documents getting the same checksum:
>> 1 / (2 ** 160)
== 6.84227765783602E-49 In other words, it's much more likely that you would win the US lottery jackpot numerous times. ;--------- Cheers, Allen K
