Is SHA-256 bad because of the NSA?

“[url=https://en.wikipedia.org/wiki/Sha-256]SHA-2[/url] is a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512) designed by the U.S. National Security Agency ([b]NSA[/b]) …”
Bitcoin uses SHA-256.
Litecoin used Scrypt.

Should we use this as an argument to prefer Feathercoin over Bitcoin?

(shrug) in my opinion it isnt a problem.

Not for us at least.

No, because it’s in the public domain, which means there’s no royalties. A hashing function has it’s own set of parameters it should be judged by… the governing body who declares it a standard not being one of those parameters.

I think the issue is more of intent rather than capability.

Until they fund a $40 billion covert mining project to steal all the coins!

Solution:

1. Change hash algorithm

2. In the meantime instill checkpointing to give them the virtual middle finger. =)

NSA are some of the best friends you never knew you had ;)

Definitely!

I picture some of the NSA guys, sitting in their ivory tower, watching down on Bitcointalk forum and having a ball. One day, when Bitcoin would become a serious thread, they register a newbie account, and their first posting are just 3 lines of code: Code that allows everybody to break the SHA-256 algorithm. ;)
