RSA Encryption Support on F5 LTM

i do see only rsa-priv and rsa-pub algorithms.

e.g.

 configuration

root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) create sys file ifile keyfile1 source-path file:///config/ssl/ssl.key/default.key
Copying file "file:///config/ssl/ssl.key/default.key" ...
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  1704  100  1704    0     0  2411k      0 --:--:-- --:--:-- --:--:--     0

root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) create ltm ifile keyifile1 file-name keyfile1
root@(ve11a)(cfg-sync Changes Pending)(Active)(/Common)(tmos)

root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm rule qux
ltm rule qux {
    when RULE_INIT {
  set static::key [ifile get keyifile1]
}
when HTTP_REQUEST {
  HTTP::collect [HTTP::header "Content-Length"]
}
when HTTP_REQUEST_DATA {
  HTTP::respond 200 content [CRYPTO::decrypt -alg rsa-priv -key $static::key [b64decode [HTTP::payload]]]
}
}

 generate encrypted text

[root@ve11a:Active:In Sync] config  echo "hello world123" | openssl rsautl -encrypt -certin -inkey /config/ssl/ssl.crt/default.crt | base64
