sha1 and sha256 aim to conform to the U.S. Government's Secure Hash Standard, FIPS PUB 180-2, although this has not been officially certified. Unlike the standard, these programs can (in principle) handle input streams that are longer than 2^64 bits. You can run "make check" to test the implementations against FIPS and SHAVP test suites.
For each filename argument, the tools print one line containing the hash value and the filename in the following format:
347b40d5e85365fa11e2c1cf6cb8c80c288c39fb filenameIf no filename is given on the command line, the input is read from stdin.
The SHA-1 checksum of this package is:
The package is configured, built, and installed by the usual commands: "./configure", "make", "make install". For details, see the file INSTALL.
