Repeat steps (5) and (4) with every 16 bytes of the message, in turn. (6) The output is the first 16 bytes of X. Although no weaknesses in MD2 have been found (see [1262]), it is slower than most other suggested hash functions.

(The standard is the Secure Hash Standard (SHS); SHA is the algorithm used in the standard.) According to the Federal Register [539]: A Federal Information Processing Standard (FIPS) for Secure Hash Standard (SHS) is being proposed. This proposed standard specified a Secure Hash Algorithm (SHA) for use with the proposed Digital Signature Standard .... Additionally, for applications not requiring a digital signature, the SHA is to be used whenever a secure hash algorithm is required for Federal applications. And This Standard specifies a Secure Hash Algorithm (SHA), which is necessary to ensure the security of the Digital Signature Algorithm (DSA). When a message of any length < 264 bits is input, the SHA produces a 160-bit output called a message digest. The message digest is then input to the DSA, which computes the signatur...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
