comment Is this way of truncating cryptographic hashes safe?
@apsillers Ah, I see what you're saying - there's a potential for collision between a pair of 3-char and 2-char base62 units where the encoding could be 3-then-2 or 2-then-3.

comment Is this way of truncating cryptographic hashes safe?
That would only be true if ONLY two base62 characters were put into the string regardless of what the three base16 characters encode to. I don't think that's the case though - I think all 3 characters are added and the string gets longer.

comment Is this way of truncating cryptographic hashes safe?
@apsillers My understanding is that they're not truncating each block, but rather concatenating all of that data together, such that there's no loss of information even if you can't trivially identify which ones were 3-char and which ones were 2-char.

comment Why Adobe is recommending McAfee security scan during flash player installation?
@MilchePatern You're talking about the general security of Flash, which is a totally different matter to this specific affiliate marketing campaign. Also, Steve Jobs was a businessman and marketing director, not an engineer or coder - his thoughts on the security of Flash are irrelevant to this particular topic. Even if we were to entertain his opinions, they mostly rely upon the complaint that Flash is proprietary, which again has little bearing on the actual security of the product.

I'm not sure how you're inferring that from the question.

If his attack model is that an attacker can't get access to the encrypted data, why encrypt the data in the first place?

comment Offline RSA strong prime test similar to Phuctor?
You should note that the factored 4096-bit key was a corrupt subkey, not a real generated key. As such it had no real-world impact.
