Right.
speaker_5HOST
The bad ones are MD5 and SHA1.
speaker_5HOST
But the reason they are bad kind of blew my mind.
speaker_5HOST
They are bad for passwords because they are fast.
speaker_5HOST
It is a brilliant paradox.
speaker_6HOST
It really is.
speaker_6HOST
If a hashing algorithm is fast, like MD5, a hacker's computer can guess billions of passwords a second.
speaker_5HOST
Billions.
speaker_2HOST
The script uses a mathematical algorithm to scramble the password before checking it.
speaker_2HOST
Specifically, it uses the MD5 function.
speaker_2HOST
I've heard some people describe this as putting the password in a lockbox.
speaker_3HOST
Actually, I really dislike the lockbox analogy.
speaker_3HOST
Exactly.
speaker_2HOST
If they match, it knows I used the right password, even though the database can't read the password itself.
speaker_3HOST
But wait, I've heard in cybersecurity circles that MD5 is considered an outdated algorithm.
speaker_3HOST
Why are we using it here?
Sec GuyHOST
For the exam, you need to recognize hashing algorithms and their life cycles.
Sec GuyHOST
First is MD5, which produces a 128-bit hash.
Sec GuyHOST
MD5 is completely deprecated.
Sec GuyHOST
It is vulnerable to hash collisions, which occur when two entirely different input files produce the exact same digital fingerprint.
Sec GuyHOST
If an attacker crafts a malicious script that yields the same MD5 hash as a trusted system file, your security controls are bypassed.
Sec GuyHOST
Next is SHA1, producing a 160-bit hash.
Sec GuyHOST
It was standard for years, but like MD5, it has been mathematically broken and is deprecated.
Sec GuyHOST
Today, the enterprise standard is the secure hash algorithm, two-family, specifically SNHA256 and SHA512.
