Is hash irreversible?
While the hash produced is irreversible, it’s not pre-image resistant! Given the hash value of 0, I can very easily produce any number of inputs that produce that hash: 2, 4, 6, 8, 10, etc.
What is reversible password?
Storing encrypted passwords in a way that is reversible means that the encrypted passwords can be decrypted. A knowledgeable attacker who is able to break this encryption can then log on to network resources by using the compromised account.
Are there black hackers?

No, they cannot be decrypted. These functions are not reversible. There is no deterministic algorithm that evaluates the original value for the specific hash. However, if you use a cryptographically secure hash password hashing then you can may still find out what the original value was.
What is a blue hacker?A blue hat hacker is someone outside computer security consulting firms who bug tests a system prior to its launch, looking for exploits so they can be closed. Blue Hat Hacker also refers to the security professional invited by Microsoft to find vulnerabilities in Windows.

How does a OTP work?
A one-time password or passcode (OTP) is a string of characters or numbers that authenticates a user for a single login attempt or transaction. An algorithm generates a unique value for each one-time password by factoring in contextual information, like time-based data or previous login events.
What is minimum password age?
The Minimum password age policy setting determines the period of time (in days) that a password must be used before the user can change it. You can set a value between 1 and 998 days, or you can allow password changes immediately by setting the number of days to 0.
Can SHA256 be decrypted?
SHA256 is a hashing function, not an encryption function. Secondly, since SHA256 is not an encryption function, it cannot be decrypted.
Is Sha-256 Collision free?
The best one could do would be a brute-force birthday attack on this function, which would require on average 40³⁸ hashes. Since executing a brute-force attack of this size is considered computationally infeasible, SHA-256 can be considered collision-resistant, for now at least.
Is it possible to reverse SHA256?
No, SHA-256 – as a function – cannot be reversed. That would mean it’s one-way property and thus the entire hash has been completely broken.
Can MD5 be decoded?
The MD5 cryptographic algorithm is not reversible i.e. We cannot decrypt a hash value created by the MD5 to get the input back to its original value. So there is no way to decrypt an MD5 password.
How do you decrypt?
