Why should account passwords be disabled instead of the account being immediately deleted quizlet?

ANSWER: Account passwords should be disabled (made inactive) instead of the account being immediately deleted. This serves to create an audit trail to conform with compliance issues, and also makes the reestablishment of an account easier if it becomes necessary.

What is the newest version of the secure hash algorithm SHA )?

What is the latest version of the Secure Hash Algorithm? SHA-2 is one of the version secure hashing algorithms. It has six variations: SHA-224, SHA-256, SHA384, SHA-512, and SHA-512/224. SHA-3 is evolved as latest version after SHA-2.

What is the basic difference between SHA 224 and SHA-512 224?

2 Answers. As stated by FIPS 186-4 (6.6) The only two differences between SHA-512 and SHA-512/224 are the eight 64-bit words used for initialization, given by FIPS 186-4 (5.3. 6.1); and result truncation to the first 224 bits of the 512-bit result: H(N)0, H(N)1, H(N)2 each 64-bit, and the high-order 32 bits of H(N)3.

Which is better MD5 or SHA256?

The SHA-256 algorithm returns hash value of 256-bits, or 64 hexadecimal digits. While not quite perfect, current research indicates it is considerably more secure than either MD5 or SHA-1. Performance-wise, a SHA-256 hash is about 20-30% slower to calculate than either MD5 or SHA-1 hashes.

Why is MD5 bad?

While MD5 is a generally a good checksum, it is insecure as a password hashing algorithm because it is simply too fast. You will want to slow your attacker down. Generate a unique, cryptographically secure random value for each password (so that two identical passwords, when hashed, will not hash to the same value).

Which is more secure MD5 or SHA1?

Both MD5 stands for Message Digest and SHA1 stands for Secure Hash Algorithm square measure the hashing algorithms wherever The speed of MD5 is fast in comparison of SHA1’s speed. However, SHA1 provides more security than MD5. The has functions can’t be restrained.

Why is MD5 still used?

MD5 is still being used today as a hash function even though it has been exploited for years. Following in the footsteps of MD2 and MD4, MD5 produces a 128-bit hash value. Its main purpose is to verify that a file has been unaltered.

Is MD5 Crackable?

You cannot un-hash an MD5 hash. There is no way of “reverting” a hash function in terms of finding the inverse function for it. As mentioned before, this is the whole point of having a hash function. It should not be reversible and it should allow for fast hash value calculation.
