Why? The FBI pitched a fit over access to a shooter’s phone in the press a few years ago, then stopped.
Now, you have a multiple products on the market that can crack passcodes by utilizing flaws that allow you to brute force PINs, which are by default 6 digit numbers. (Despite most guidance demanding 8)
I have no idea if anyone has covered it. It's industry knowledge. Source: me
I figured it would be generally known at this point, especially with the whole perceptual hash debacle (intended to satisfy LEAs despite the plan to finally enable image encryption). I'm not sure what the internal politics looked like after the perceptual hash snitch got axed - my friends who would know quit Apple by then.
>Later provision was added to allow export of 56-bit encryption if the exporter promised to add "key recovery" backdoors by the end of 1998.
First SSL crippled to 40-bit RC2/RC4
First 802.11 wireless protocol WEP "64" key length shortened to 40 bits
