Technicians are testing the security of an authentication system that uses passwords. When a technician examines the password tables, the technician discovers the passwords are stored as hash values. However, after comparing a simple password hash, the technician then discovers that the values are different from those on other systems. What are two causes of this situation? (Choose two.)Select one or more:Both systems use MD5.One system uses hashing and the other uses hashing and salting.Both systems scramble the passwords before hashing.One system uses symmetrical hashing and the other uses asymmetrical hashing.The systems use different hashing algorithms.
Question
Technicians are testing the security of an authentication system that uses passwords. When a technician examines the password tables, the technician discovers the passwords are stored as hash values. However, after comparing a simple password hash, the technician then discovers that the values are different from those on other systems. What are two causes of this situation? (Choose two.)Select one or more:Both systems use MD5.One system uses hashing and the other uses hashing and salting.Both systems scramble the passwords before hashing.One system uses symmetrical hashing and the other uses asymmetrical hashing.The systems use different hashing algorithms.
Solution
The two causes of this situation could be:
-
One system uses hashing and the other uses hashing and salting: Salting is a technique where a random value is added to the password before hashing. This results in different hash values even for the same password, increasing security by making it harder for an attacker to guess the password based on the hash.
-
The systems use different hashing algorithms: Different hashing algorithms produce different hash values. Even a small change in the input (the password, in this case) will produce a drastically different hash value. So, if one system uses, for example, MD5 for hashing and the other uses SHA-256, the resulting hash values for the same password will be different.
