adding new encryption algorithm to OpenSSL

[M. V.]

hi,

for a project, i have to add my own encryption algorithm to racoon (part of 
ipsec-tools) in freebsd. i realized racoon uses openssl libraries for 
encryption 
algorithms. so, i wanted to know , does anyone have any experience in doing 
such 
thing? does anyone have any suggestions for me?

1- what's the best and easiest way? adding my algorithm to racoon, openssl or 
else (as a dynamic library, etc)?
2- is there any example, code template or documentation which could help me 
doing this?

thank you.
