porting from Linux to Windows - RC5 Decryption

Hi,

I am trying to port a dissector from Linux to Windows. The dissector requires rc5 encryption/decryption capability and the Linux code uses openssl rc5 header files. It seems wireshark doesnt use openssl instead uses GNUTLS. I am wondering if there is a way to use openssl for wireshark dissector development ? if yes, what changes are needed in the source code ? also are there any pros and cons of trying to do that ?

Thanks,

Am.
