It should take about 2**n steps to find a message with the same digest as a given message and 2**(n/2) to find any two messages with the same digest, when n is the digest size in bits. Therefore, this algorithm can serve as a means of providing a "fingerprint" for a message.<p> +Portability Issues: SHA-1 is defined in terms of 32-bit "words". This code uses <stdint.h> (included via "sha1.h" to define 32 and 8 bit unsigned integer types. If your C compiler does not support 32 bit unsigned integers, this code is not appropriate.<p> +Caveats: SHA-1 is designed to work with messages less than 2^64 bits long. Although SHA-1 allows a message digest to be generated for messages of any number of bits less than 2^64, this implementation only works with messages with a length that is a multiple of the size of an 8-bit character.<p> +<dl compact><dt><b>Id</b></dt><dd><a class="el" href="a04943.html">sha1.cpp</a>,v 1.4 2003/10/20 16:10:17 lecroart Exp </dd></dl> + +<p> +Definition in file <a class="el"
