Greetings!

I have this code,

char[] CalculateMD5(byte[] Buffer)
{
char[] ehash = "return";
ubyte digest[16];
MD5_CTX context;
context.start();
context.update(Buffer[0..length]);
context.finish(digest);
printDigest(digest);
for (int i=0; i<digest.length;i++)
writefln(digest[i]);
//ehash = digest;
return(ehash);
}

I need to change digest to be a char[].  I tried

std.string.toString(digest)

but I get this error:


21:38:36.05>dmd DeleteTokens.d ws2_32.lib
DeleteTokens.d(383): cannot implicitly convert expression digest of type
ubyte[16] to char[]

Any ideas?

thanks.

You can try explicitly casting it... but, really, remember that you 
won't get a string per say, but rather bytes... it really *is* bytes.

You don't want to convert it to a hexadecimal string, do you?

Yeah, I do want it hex.  But, after posting, I did a search, :-) and guess what?
I found the code:

char [] ChangeToChar(ubyte[] digest)
{
char[] strOut;
foreach (ubyte b; digest)
strOut ~= std.string.format("%02x",b);
return(strOut);
}

I posted there for easier search. :-)

thanks.

I have a suggestion for the d folks, perhaps we could add a toString to the md5
library. So,

char[] hash = digest.toString();

or something like that.

just a thought...

Y'all might want to check out the Deimos library:
   http://www.dsource.org/projects/deimos/

I wrote some basic crypto functions for MD2, MD4, MD5, SHA0, SHA1, SHA256,  
SHA512, Tiger, including a templated function for producing a hex string  
of the various digests.

To see the source itself:
