- You might want to double-check the "in the clear" statement. RFC 4253 (among others) state that the two systems involved in an ssh connection first exchange identification strings. Immediately afterwards they exchange keys and an encryption algorithm and key will be negotiated during the key exchange. When encryption is in effect, all packet payloads must be encrypted. All this happens before you ever see a login: prompt.doneal24– doneal242013-11-07 17:36:48 +00:00Commented Nov 7, 2013 at 17:36

- "I STRONGLY (and I can't make that bold enough). Suggest you allow only PublicKey based authentication for any ssh servers that you have running on the internet." --> unfortunately it is not my responsibility to choose what method, it is external providers sFTP who choose what is the best for them and we have to fit their choices. Some providers also have firewall rules to enable only our (and others authorized companies) IP(s).рüффп– рüффп2013-11-08 08:55:44 +00:00Commented Nov 8, 2013 at 8:55
- "So the key you generate on your local machine can have (and does by default) a password to decrepit it" --> I guess you are talking about the passphrase here. I made the distinction between password (to connect to the remote server) and the passphrase (to enable key extraction).рüффп– рüффп2013-11-08 08:57:00 +00:00Commented Nov 8, 2013 at 8:57

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
