Could you elaborate on what didn't work for you? The following works for me using iRule encryption:
profile persist my_cookie {
defaults from cookie
cookie mode insert
cookie name "pcookie"
}
rule my_rule {
when HTTP_REQUEST {
HTTP::cookie decrypt pcookie "mypassphrase"
if { [HTTP::uri] == "/cookiedecrypter" } {
HTTP::respond 200 content "Your cookie decrypted to: [HTTP::cookie value pcookie]"
return
}
}
when HTTP_RESPONSE {
HTTP::cookie encrypt pcookie "mypassphrase"
}
}
virtual http_vip {
pool http_pool
destination 10.3.3.127:http
ip protocol tcp
persist my_cookie
rules my_rule
profiles {
http {}
tcp {}
}
}
Here's some sample output:
[root@v9dev1 root] telnet 10.3.3.127 80
