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. It is now considered legacy and should be avoided when possible. S. 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.

The availability and overall security of the WAN edge and the branch/SOHO is thus critical to global business operations and teleworker or partner access. Figures 28-9 and 28-10 depict typical WAN edge and branch topologies.
Brute-force attacks on 3DES are considered unfeasible today. Because the basic algorithm has been well tested in the field for more than 35 years, it is considered very trustworthy. For several years, it was recognized that DES would eventually reach the end of its usefulness. In 1997, the AES initiative was announced. AES was chosen to replace DES and 3DES, because the key length of AES is much stronger than that of DES, and AES runs faster than 3DES on comparable hardware.
