Response to: Patent status?
SHA-1 is not patent-encumbered, according to this letter from NIST dated June 24, 1998: http://grouper.ieee.org/groups/1363/P1363/letters/NIST.txt .NET, Java, Perl, Python, and PHP all come with SHA-1 implementations, and there are multiple public domain SHA-1 implementations as well.
