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. Day 29 13 ■ Secure Hash Algorithm 1 (SHA-1): SHA-1 takes a message of up to 2^64 bits in length and produces a 160-bit message digest. The algorithm is slightly slower than MD5, but the larger message digest makes it more secure against brute-force collision and inversion attacks.
With the hierarchical topology, CAs can issue certificates to end users and to subordinate CAs, which in turn issue their certificates to end users, other CAs, or both. The main benefits of a hierarchical PKI topology are increased scalability and manageability; trust decisions can now be hierarchically distributed to smaller branches. 24 31 Days Before Your CCNA Security Exam Figure 28-3 Hierarchical CA Topology Root CA Subordinate CAs Bob Steve Alice Mary Another approach to hierarchical PKIs is called cross-certifying, as shown in Figure 28-4.
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). The basic four properties of digital signatures are that (1) the signature is authentic, (2) the signature is not forgeable, (3) the signature is not reusable, and (4) the signer cannot claim later that they did not sign it. Digital certificates are used to authenticate and verify that a user sending a message is who they claim to be.
