Title: sha-1 is broken
Post by: ggnfs000 on February 25, 2017, 06:11:01 PM
current news shows:
11 years of computation with 1-gpu using new efficient "algorithm" compared to 6500 years.
git uses sha-1. Probably wont take long before 1-gpu can do it in matter of hours while one leave home and come back after hour.

bitcoin uses sha-256 bit, here says, underlying concern is btc development community uses git which is sha-1.

tpm1.2 (trusted platform module) uses sha-1 and i believe, server are still shipping, although tpm2.0 with algorithm agnostic (thus can use 256) started shipping.

Long story short: move to a higher level of encryption. Lower levels don't break, they slowly erode, with plenty of warning time prior to their end of usefulness.

yes it does not looks like a sudden danger, rather an imminent danger.
