Google has found a way to create collisions in SHA-1.
Cryptography functions using sha-1 now becomes a risk
Google security blog
The
Shattered link demostrates the proof.

Amazing.
I cannot imagine any public encryption algorithms or other methods not already cracked by big GOVs.

It's a hash, not encryption. Not sure they have all encryption broken. Someday, yes, due to power.

hash is based on a count in the encryption?

Hashing creates a fixed length of text that is not reversible and hopefully doesn't generate the same output for different inputs. (collisions)
Encryption hides the text, is not a fixed length and is reversible. Obviously, one wants that decode to only be possible with the proper key.
They are different processes.
