Which command creates new directories in Linux?

Bob sent a confidential, encrypted message to Alice using asymmetric cryptography. What key should Alice use to decrypt the message?

A one-way hashing function is designed to be:

True or False? A drawback to public key infrastructure (PKI) is that the two parties must have prior knowledge of one another in order to establish a relationship.

True or False? A one-way hashing function is designed to be relatively easy to compute in one direction but extremely difficult to reverse.

True or False? For both symmetric and asymmetric cryptography, data is encrypted by applying an encryption algorithm to a key.

True or False? A man-in-the-middle (MitM) attack is carried out when an attacker gets between two users with the goal of intercepting and modifying packets.

Reconnaissance, scanning, infiltration and escalation, exfiltration, access extension, assault, and obfuscation are considered:

True or False? Whereas the primary goal of a penetration test is to determine whether a specific resource can be compromised, a vulnerability assessment is a survey of a system to identify as many vulnerabilities as possible.
