Calculating Checksum of a file

[nitroprog]

Hello,

I need a function in C language that calculates the checksum of a file. If you know were i can find it or if you have something that can help me, i appreciate it.

Since the guts of the problem is only a single line...

while ( (ch=fgetc(fp)) != EOF ) sum += ch;

Variable declarations and file opening/closing are left as easy exercises.

If you are looking for MD5 checksums, there is source code attached to RFC 1321 (

http://www.ietf.org/rfc/rfc1321.txt).
