Why would you use an MD5 algorithm?
MD5 is most commonly used to verify the integrity of files. However, it is also used in other security protocols and applications such as SSH, SSL, and IPSec. Some applications strengthen the MD5 algorithm by adding a salt value to the plaintext or by applying the hash function multiple times.
What companies use MD5?
Some of the projects that use MD5 as the default method for storing user passwords include WordPress, osCommerce, SuiteCRM, miniBB, SugarCRM, CMS Made Simple, MantisBT, Phorum, Observium, and X3cms.
Why is hashing well suited for passwords?
Password hashing requires the following properties: Have a unique salt per password (salt may only be used once across the database containing all password hashes) to prevent a bruteforce attack of compromising the data in one run. Fast on software (executing the function once must be relatively fast)
What kind of hashing algorithm does MD5 use?
MD5 is a password hashing algorithm similar to that of SHA-1. LinkedIn’s Vicente Silveira said on Wednesday the company has increased its security “which includes hashing and salting of our current password databases.”
Why is MD5 used to store passwords in a database?
MD5 is a cryptographic algorithm, often used to store passwords in a database. In the early days of the Internet, websites mostly kept clear text passwords in their databases. It wasn’t a good solution, so developers used MD5 to obfuscate the password in the database.
How is MD5 used to obfuscate passwords?
In the early days of the Internet, websites mostly kept clear text passwords in their databases. It wasn’t a good solution, so developers used MD5 to obfuscate the password in the database. MD5 is an algorithm that produce a 32 characters hexadecimal string from any password, phrase or text.
Which is the best reason to not use MD5?
As the sensitivity of what you’re doing and your dependence on the irreversibly of the cryptographic hash increases, so the danger in using MD5 also increases. But the best reason to not use MD5 is the same as the best reason for not using triple-DES: There are better options available, and no advantage to use the old algorithm.
