md5/sha1

Discussion in 'C Programming' started by Rafal 'Raf256' Maj, Jul 5, 2003.

  1. Hello,
    where can I find ready to use functions for hasing into md5 and sha1 ?

    I.e. ansi C code like:

    void makeMd5(unsigned char* input, long size, unsigned char* output) {
    ....
    }

    Ready to copy/paste into application?

    What is the license for SHA1/MD5 can I use it in my commercialn
    application?

    Can You point me to some other news groups that would be good for this
    question?

    TIA

    The question isn't appropriate here; I'm not sure in which newsgroup
    it might be. However, google can often be of service :)

    RFC 1321 defines the details of the MD5 hashing algorithm, and
    includes old traditional-style source code. The source code can be
    used as-is, free-of-charge, and free for any use whatsoever, provided
    that your program identifies itself as a derivative of the "RSA Data
    Security, Inc. MD5 Message-Digest Algorithm". Unfortunately, you'll
    need to remove headers and footers from each page, but this can be
    done fairly painlessly; also I'm sure you may find header- and
    footer-less versions somewhere.

    This is at http://www.ietf.org/rfc/rfc1321.txt

    A definition and accompying source code for SHA1 is also available, in
    RFC 3174; http://www.ietf.org/rfc/rfc3174.txt

    HTH, HAND.
