Hi readers,

I will be glad to hear the usage of MsgDigest API. I am coding Message digest for Outgoing Messages (Instant Messages). I want to know what is the relation between the MD5 hash algorotam and the MsgDigest API. can i use this API for MD5 digest . Please explain with example. early answer is appriciated.

Hope any one tell me is there any thing in symbian which supports the MD5 algoritam  Afro

Regards

Re: MD5 in symbian
hi,

I too am looking for Symbian APIs for algorithms like MD5- SHA1. But, it seems these are internal APIs.

May be I am missing something.

Hoping for some reply.

Thanx and Regards,

Smiley

Re: MD5 in symbian
the APIs are private, and available only with the private SDK...

anyways,
MD5 is broken. Use SHA-1.

Re: MD5 in symbian
Hi,

Thanx.

So, now I am left with options for either porting  some algorithms to Symbian or have my own implementation for these.

I am working  on implementation for a system, that could encrypt payloads for peer to peer message communication.  Somewhat, similar to IPsec implementation for applications, that are system aware ( i.e. they participate in security association).

It would also work fine for me, if I could get a 3rd party support like VPN client support from Nokia, and could use my application to set security parameters( like encryption algorithms) for IPsec.

Thanx in advance for any pointers in these reagrds.

Rgds,
Smiley

hi All

I am looking for symbian API based on any asymmetric algorithm.
Please do reply

Re: MD5 in symbian
There are two asymmetric algorithm.

RSA and encryption based on Elliptical curve cryptography, out of which RSA implementation is provided by symbian.

But this is also private.

there are third party vendors who provide libraries for the ECC implementation for small handheld devices.

anyways...
Implementation os symmetric encryption algorithm AES can be found at...

Re: MD5 in symbian
Thanks Vinay,
The link which u have given me.
IS this is of third party.
If I wants to implement RSA then which libraries do i need.
which API could implemented RSA algo.
Help Please

Re: MD5 in symbian
If you were to implement RSA. you'll just dont need any libraries. You'll have to write everything from scratch.

there are few free source codes for RSA in java and C++. you'll need to port them to Symbian.

Re: MD5 in symbian
you dont need any symbian API. Just require the algebraic operation like multiplication, division etc..

C++ and java source code available at...
