Government requires by law for use in certain applications. The SHA-2 family includes 224-bit, 256-bit, 384-bit, and 512-bit functions. When choosing a hashing algorithm, use SHA-256 or higher, as they are currently the most secure. CAUTION: Security flaws were discovered in SHA-1 and MD5. Therefore, it is now recommended that these algorithms be avoided. Authentication Using Hashing Two systems that have agreed on a secret key can use the key along with a hash function to verify data integrity of communication between them by using a keyed hash.
Digital Signatures and RSA Certificates Digital signatures provide the same functionality as handwritten signatures. Specifically, they are a mathematical technique used to provide three basic security services: authenticates a source, proving that a certain party has seen and signed the data in question; guarantees that the data has not changed from the time it was signed; proves to a third party that the data exchange did take place. Digital signatures are commonly used in code signing (to verify the integrity of downloaded files) and digital certificates (to verify the identity of an organization or individual).
There is no unique identifying information from the sender in the hashing procedure. Therefore, hashing is vulnerable to man-in-the-middle attacks and does not provide security to transmitted data. The following are the three most commonly used cryptographic hash functions: ■ Message Digest 5 (MD5): MD5 is a one-way function that makes it easy to compute a hash from the given input data but makes it very difficult to compute input data given only a hash value. MD5 produces a 128-bit hash and is now considered a legacy algorithm that should be avoided.
