You mean the specifications?  RFC 4120, at any IETF RFC mirror, has  
the ASN.1 specification of the messages.

Or the code implementing it?  In the MIT distribution, src/include/ 
krb5/krb5.hin and src/include/k5-int.h include the C data structures  
corresponding to various messages (and a bunch of other stuff), and  
src/lib/krb5/asn.1 has the code that converts between the C and  
network representations (but it's pretty ugly, hard to understand, and  
harder to modify).
