Lyor Goldstein commented on SSHD-1189:
--------------------------------------

{quote}I have this property in the property file (all are deprecated but some 
legacy clients use it)

SSHKeyExchangeAlgList=diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,rsa2048-sha256,rsa1024-sha1

Now how will we map this algorithm in the String to type KeyExchangeFactory, is 
there any utility function which can help here?
{quote}
{{BuiltinDHFactories#parseDHFactoriesList}} (and also for the ciphers, MACs, 
etc,). Note that specifically for {{KeyExchangeFactory}} the result is not a 
{{KeyExchangeFactory}} but rather a {{DHFactory}} from which 
{{KeyExchangeFactory}} can be instantiated. This is due to the fact that unlike 
ciphers or MACs, the implementations for client and server are +different+ - 
see {{newFactory}} factory methods in {{DHGClient, DHGEXClient, DHGServer, 
DHGEXServer}} classes. Note that each one of them supports a +different+ subset 
of KEX algorithms as indicated - see the respective {{ClientBuilder#DH2KEX}} 
and {{ServerBuillder#DH2KEX}} that you can use in order to convert a parsed 
{{DHFactory}} value to its respective {{KeyExchangeFactory}} instance
